Constitution



Constitution (also known as health, previously Hitpoints or HP) is a skill that controls how many Life points (LP) a player or monster has. Life points represent the amount of damage a player or monster can withstand until it dies. Death occurs when a player's or monster's life points reach zero. The maximum number of life points a player may have without boosting is 10 times his or her Constitution level.

Players begin with 100 life points and a Constitution level of 10, with 1,154 experience, and at level 99 Constitution, players will have 990 life points.

The number of life points a monster has varies between 1 and 30,000. Nex, the highest level monster in RuneScape, tops this list, followed by Corporeal Beast, Hati, Nomad, Turkey (2009 Thanksgiving event), Decaying avatar, Pest Queen, Living rock patriarch, Skeletal horror, Tormented demon, Ice strykewyrm, Living rock striker, Kree'arra, Commander Zilyana, General Graardor, K'ril Tsutsaroth, and the Kalphite Queen (the Kalphite Queen has two forms, each of which has 2,550 life points, effectively giving her 5,100 total life points). The title of monster with the lowest amount of life points are the Evil creatures from the quests The Eyes of Glouphrie and The Path of Glouphrie with only 1 Lifepoint. However, Xenia from The Blood Pact appears to have only 4 life points but is never fought, only attacked in a cut scene. Later, she reveals that she was pretending to be hurt worse than she actually was, so she may therefore have more than 4 life points. In the Temple of Ikov quest, Lucien only has 1 life point, but you can only fight him once.

The Steel Titan has the highest amount of life points for a summoning familiar at 7500 life points.

However, the Wise Old Man is speculated to have the largest amount of lifepoints, as during the quest Swan Song, the Wise Old Man is hit for almost 2500 lifepoints, yet his health bar does not even seem to decrease by a single bit. This can mean that the Wise Old Man has more than 30,000 lifepoints, more than Nex.

Fighting
Any player or creature who is hit in a fight will have a life bar shown above them, which represents their life points. There are two colours on the bar: green and red. The green part of the bar is on the left and represents how many life points the player has remaining. The red part of the bar appears on the right and represents how much damage has been taken away from their maximum life points. This allows an easy estimation of the percentage of health a player has left.

Players may look to the top-right of their RuneScape screen to check how many life points they have remaining. They will be alerted when their life points drop to 25% or lower as the Life points status globe will start to pulse. Due to a recent hidden update, players are now further warned that their life points are getting low (25% or less of total LP) through the addition of a beating heart sound effect which accompanies the pulsing animation until health is restored above 25%. (This is a very common device in video games and is almost always used to show that the player is near death or that another similarly dramatic event is occurring.)

Poison (Members only)
A player may become poisoned during a fight. This effect will continue to reduce life points periodically, even after the fight is over. The body's natural defences will gradually neutralize the poison, however. For instance, if a player is hit by another player wielding a poisoned dagger or spear, they would be hit for 48 damage initially, then 46, then 44, and so on until the damage hits 10, by which time the player would have been naturally cured of the poison. Players may cure the poison at any time with an antipoison potion made using the Herblore skill.

Please note that if you are poisoned in a Members' server but then switch to a Free server, you will remain poisoned with no way to cure it (aside from eating food to offset the damage) until you switch back to a Members' server.

Death


If a player is in Pest Control, in a player-owned house, duelling another player at the Duel Arena, or playing any other safe activity, he or she will not lose any items on death, and will respawn in a designated location with all items retained.

A ring of life can also teleport the player safely back to the chosen respawn point automatically upon reaching 10% or below their maximum LP. There are three exceptions: either the player was hit for more than 10% of his or her maximum LP, is beyond level 20 in the deep wilderness, or is in a safe activity with no danger of losing his or her items. A Ring of Life can only be used once before it's charge is finished.

In addition, if a player has used the Abyss for runecrafting, he or she is given a skull that appears over his or her head. If a player dies of any circumstances while being "skulled," he or she loses ALL of his or her items carried at the time instead of the usual all but three. However, if a skulled player dies while the Protect Item Prayer is on, he or she keeps ONE item (one more than the usual, which is zero if the player is skulled). If a player does not enter the Abyss within twenty minutes of receiving the skull, the skull vanishes. The same circumstances apply if a player has attacked another player in the wilderness.

Respawning
When a player dies, he or she will respawn, meaning he or she will live again. Normally, the player will keep three of his or her items (s)he was carrying (see above for exceptions).
 * For free players, they will always respawn in Lumbridge, as it is set as their home town.
 * For members, they will initially respawn in Lumbridge, as it is the default home town. After completion of some quests, members can change their respawn point to:
 * Falador, after completion of the Recruitment Drive quest;
 * Camelot, after completion of the King's Ransom quest and the Knight Waves Training Grounds miniquest;
 * Soul Wars lobby, after completion of the Nomad's Requiem quest.

Earning experience


To earn experience in Constitution, a player has to fight or do a quest that rewards Constitution experience. Alternatively, one could use an item that gives a specific amount of experience. (Ex: xp lamp)

When fighting, whenever a player deals damage, he or she will always earn Constitution experience. The amount of experience earned is found using the formula $$damage * 0.133$$. The sole exception to this is when a player uses a Dwarf Multicannon as it gives half the range experience normally received and no Constitution experience. Constitution experience is earned at one third the rate of Attack, Ranged, Strength and Defence, making this one of the slowest skills to train although it may be gained fast if you are focusing on Attack, Strength, Defence, Ranged or Magic too.

The quickest way to earn Constitution experience is the Soul Wars activity. By using Soul Wars, achieving 99 Constitution at a low combat of 25 is possble, thus being the lowest level possible with a Constitution cape.

Prayer cannot help train Constitution but using Rapid Heal or Rapid Renewal can help bring back health if you've lost some.

Recovering life points


A player can heal to restore their life points back to its maximum. There are a number of ways to do this:


 * Let it recharge on its own. A player will naturally heal one life point about every six seconds. However, this is very slow, although the prayers Rapid Heal and Rapid Renewal doubles life point recovery rate to one every three seconds, and 5 times the recovery rate, respectively. This is not recommended unless you have no food, are next to an altar, training with very weak monsters, or do not want to get killed by whatever monster, PKer, or NPC happens to be there. Also, a lunar spell, Dream, will make life points recover five times as fast as normal. Additionally, a Regen bracelet will double recovery.
 * Eating food. Players can eat food to heal their life points, the best foods are more expensive but providing more healing per item. This is the most common way players heal themselves. Members have a much wider variety of foods available to them, most of which can heal more life points at once.
 * Drinking Potions. Members have access to Saradomin Brews, which heal 15% of a player's total life points and adds it to their life points. This can exceed their limit. The Overload potion also replenishes a player's lost HP (when drunk) in intervals after drinking it.

The recovery rate for life points, in life points per minute, is given by the formula $$10 * (1 + bonus)$$ where bonus is indicated in the chart below.

* Note: resting, listening to a musician, and the dream spell cannot be combined.

** Note: the Rapid renewal and rapid heal prayer cannot be used together.

The maximum life point recovery rate without a familiar is 100 points per minute (with rapid renewal, dream, and a regen bracelet). The rate for free players would be 40 points per minute (with rapid heal and listening to a musician)


 * Without any skills a player can only sit and get 2x lifepoint restoration.
 * All restorations are treated as separate clocks. Resting/Listening to music/moving status on player is treated as one clock while prayer restoration is treated as another clock. If a player is listening to music with rapid heal, he will gain 1 lifepoint for every 2 seconds, plus another 1 point for every 6 seconds in another interval. However the effect overally stack and it leads to 4 points every minute, but irregular through the minute.
 * The monks at the Monastery and Entrana will heal players if they ask them. They heal 20% of the player's life points level.
 * The nurses Sabreen and A'abla and Surgeon Tafani at the infirmary north of Al-Kharid Duel Arena will heal players if asked.
 * Two lunar spells can be cast to heal a player or a group of players: Heal Other, level 92 magic needed, and Heal Group, level 95 magic needed.
 * Die. When a player dies, they respawn at full health and full energy. This is not recommended unless the player has banked all items and wants to go to an area near their respawn point.
 * A player can use a bracelet of regeneration which doubles life points recovery rate. When used in conjunction with the prayer rapid heal, it triples to 30 lifepoints per minute.
 * Using Soul Split (one of the Ancient Curses, level 92 Prayer required) adds 1/5th of damage dealt back to lifepoints. Since this method needs high hits to heal fast, it can be used together with Turmoil. It is risky to use versus NPC capable of dealing high and/or frequent damage though. Used right, it is a great and potion-saving alternative against monsters usually fought with activated protection prayers or deflection curses.
 * Some weapons have special attacks that recover life points, such as Enhanced excalibur, Saradomin Godsword, Saradomin bow and Guthix bow. Additionally, the Guthan's set effect, will occasionally heal a player by the amount they hit.
 * The two Summoning familiars, the Void spinner and the Bunyip, will heal a player over time, for 10 life points per 15 seconds and 20 life points per 15 seconds, respectively. The Unicorn stallion will heal 15% of the player's life points by using its special move, Healing Aura.

Boosts to life points

 * Saradomin brew - Made using the Herblore skill. Drinking this brew raises defence by 25% and life points by 15%+20 even above maximum, though all other combat skills decrease by 10% excluding defence and prayer.
 * Titan's Constitution - The respective scroll of the Fire titan, Moss titan and Ice titan which will raise a player's maximum life points by 80 and defence by 12.5% temporarily.
 * Elidinis Statuette - this altar in Nardah will heal you and raise your total LP by 80, and will also refill your prayer. Players need to have completed Spirits of the Elid.
 * Guthix rest - Guthix rest, if drunk when at full life points, will boost your maximum life points by 50.
 * Oo'glog - by resting in the Thermal bath your LP will be raised dramatically, by 20% over your maximum life points.
 * Temple Trekking / Burgh de Rott Ramble - One particular event in the treks Abidor Crank, temporarily increases your max LP according to its max level / current stance, as well as increasing defence in the same way, and turning all rotten food in your inventory into curry or stew.
 * Rocktail - Can heal up to 100 over the player's maximum life points when eaten.
 * Torva, Pernix and Virtus armour - Wearing a head-slot, body-slot and leg-slot will boost your maximum lifepoints by 66, 200, and 134 respectively, for a total of 400. This is not a set effect and each item will grant its bonus regardless of other equipment.

Boosts to Constitution

 * Constitution Cape of Achievement - Owners of a Constitution Cape can boost their Constitution skill by 1 every minute, by operating the cape or re-equipping it. The Constitution Cape is one of the Capes of Achievement, which can be bought and equipped by players with 99 Constitution only. The cape is sold by Surgeon General Tafani at the Duel Arena in Al Kharid for 99,000 coins.

Trivia

 * The fastest regeneration you can achieve without eating, using potions, special attacks, or summoning scrolls is 200 life points a minute. This is using the Dream spell, the Rapid Renewal Prayer, the Regen Brace, and a Bunyip.
 * If you levelled Constitution before the 3 March 2010 update, it would show Hitpoints in your Adventurer's Log. It was changed to Constitution the following day.
 * After a hidden update from Jagex on December 2008, falling below 25% of maximum life points will result in a heartbeat sound.
 * Sometimes when you have a connection loss, your life points may go to 0, and the heart beating sound occurs, but you do not die; you stay right in the place you were in when the connection lost happened.
 * When RuneScape 2 was released, the experience required for level 10 in any skill was increased slightly. This meant that characters that had not gained Constitution experience in RuneScape Classic were brought to RuneScape 2 with only level 9 Hitpoints. Despite this, the players were still level 3 combat.
 * In RuneScape Classic the skill was called "Hits". It was renamed Hitpoints upon the introduction of RuneScape 2 and subsequently renamed Constitution with the Hitpoints skill update.
 * On 3 March 2010 the Hitpoints skill was once again renamed, this time to Constitution. However, this update also changed the way the skill worked - multiplying all damage, healing, and health by 10 - and separating player's health from the skill. Before the update, upon losing health, a player's Hitpoints level would decrease, much like Prayer or Summoning.
 * The name change for this skill was probably the most significant. The only other skill name changes were Tailoring to Crafting, PrayGood/PrayEvil to Necromancy then Prayer, Herblaw to Herblore, Runecraft to Runecrafting, and Defense to Defence.
 * A player concentrating on just one melee skill (Attack, Strength or Defence), will have to inflict 32,586,080 life points of damage to get from level 1 to 99. For level 99 in all melee skills, a player needs to inflict 97,758,230 life points of damage.
 * On 27 May 2009, the life points bar and damage splats were graphically updated. Before this update, the life points bar was simply a bar that had only green and red colour. After this update, an outline was added and the colours had more detail. Additionally, NPCs with many life points, such as the Corporeal Beast with 20,000 life points, received a much longer bar in order to more accurately display the amount of life points lost.
 * If you are poisoned on a members' world, you will remain poisoned if you switch to a free-to-play world. The same applies if you are diseased.
 * As of the 20 October 2009, the life points bar will no longer become completely red unless the monster or player has zero life points.
 * In the Mobilising Armies activity, neither damage nor health was increased during the Hitpoints skill update.
 * Previously, if a player had only 50 LP left, assuming that they have 300+ maximum LP, then the bar on top of them would change shade to be mostly red, meaning they are near death. However, due to a hidden update in June 2009, the health bar above your head will no longer change shades.
 * Fairy Nuff in Zanaris still speaks of hitpoints even after the update.
 * During the 2010 Easter event, there existed a bug wherein Fluffy the squirrel could be attacked upon being summoned. Fluffy would die after taking 1 damage, giving him the lowest amount of life points in the game. However, this bug has since been fixed.
 * Although Constitution was said to be the same as hitpoints and not affect damage or defence overall, there are many examples that oppose this statement. Failing agility obstacles now have higher damages such as 33 instead of the previous 3 which should be only 30 now, as well as poisoning monsters such as the snakes. This however, is a good debate due to the fact that the damage may in fact have remained the same. The theory behind this is that jagex had a rounded display number, such as 3, that would have been calculated a second or so before the hit actually took place. All they did was multiply the damage x10 and the constitution by x10 to give you a maximum LP of 990 (with level 99 constitution unboosted). By doing this the damage formula was not altered, however the game has to show a hit 10x. So before the update a 3 would have been seen, but the hit may have actually been 3.3 or something of that nature. 3.3 x 10 = 33, to us this is an odd number being used to seeing even numbers like 3. if you have 5 lp left you will see that now the system will add correctly to hit 5, but it would be an odd number, in this case if the next hit was a kill shot it would be 17. Before the update due to the numbers always rouding down, a current 17 would have been shown as a 1, meaning that currently 33 + 17 = 50 but 3 + 1 = 4, meaning that the amount of damage overall has increased.
 * A hitsplat of 1000 may be achieved by using the penance trident on experiments - if the special hits or by using ruby bolt(e) against high health monsters.
 * In a player poll, the last question asks whether you would like to see the Daemonheim hit-splats in the rest of RuneScape. This is a sign that the Dungeoneering healing hit-splat might soon be coming into the rest of Gielinor.
 * If you eat food while in combat, the green portion of your life bar will increase when a monster attacks you, making it look like the monster's attack has healed you.
 * New hit-splats, called the hit marks system, were released on 14 December 2010. With those new hit-splats, you can now see what type of damage your opponent inflicted (melee, magic, or ranged), allowed you to see (in a group fight) if you or a teammate inflicted the damage (lighter red means you inflicted it, darker red means someone else inflicted it), and informs you with a golden hit-splat if you inflicted your max damage. The update also changed the looks of the hit-splats.
 * The highest number of life points a player can have at one time is 1,680. This is achieved by wearing a full set of Torva, Pernix, or Virtus armour, equipping a Cape of Constitution and boosting to 100/99, and then quickly jumping into the Thermal Pool in Oo'glog. (An easier, more portable way to boost involves a Saradomin Brew, though the highest a player can reach using that is 1,610.)
 * A jagex moderator, can set whatever level of life points they want. As shown on the screenshot taken by a jmod during an event that was later posted on the Runescape fan page on Facebook.
