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 before 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 any boosts is 10 times his or her Constitution level.

Players begin with 100 life points and a Constitution level of 10, and their Lifepoints are increased by 10 for Constitution every level gained. As such, a player with level 99 Constitution will have 990 life points.

The number of life points a monster has varies between 1 and 50,000. Har-Aken tops this list. Nex, the highest level monster in RuneScape, follows, tied with Char, the quest boss of The Firemaker's Curse, followed by Corporeal Beast tied with Sköll and Hati, Nomad, Turkey (2009 Thanksgiving event), Decaying avatar, Pest Queen, Glacor, Living rock patriarch, Skeletal horror, Tormented demon, Living rock striker, Ice strykewyrm, 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 Life point. 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, followed by the Pack yak and Iron titan.

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 could 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 the left of the minimap) 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 the higher levelled antiposions will give a player temporary immunity to any poison-based attack. This is especially usefull in the Pyramid Plunder Thieving Minigame.

Please also 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 30 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 its charge is finished.

In addition, if a player has used the Abyss for runecrafting, or attacks another player in the Wilderness, 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.

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).
 * Free players, can choose to respawn in Lumbridge, or at the last major hub.
 * For members, they will initially have the same options, but can gain additional ones by completing quests:
 * 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 (for example, experience lamps or quest rewards).

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 possible, thus being the lowest level possible with a Constitution cape.

Prayer cannot help train Constitution, however using the Rapid Heal or Rapid Renewal prayers, or the Soul Split Curse can help to restore health if you've lost some.

Recovering life points


A player can heal to restore their life points back to or even over 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 against very weak ennemies, or do not want to get killed by whatever monster, PKer, or NPC happens to be there. Also, the lunar spell Dream will make life points recover five times as fast as normal. Additionally, a Regen bracelet will double recovery. Resting in conjunction with the prayers Rapid Heal and Rapid Renewal also accelerates healing.
 * Eating food. Players can eat food to heal their Life points. The best foods are often more expensive but provide more healing per item, and depending on which item it may also have other bonuses,such as increasing your maximum health. Note that any health boosted over your maximum will fall naturally over time. Food is concidered the most common way for 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.
 * Special attacks. The special attack of Enhanced excalibur will heal a players lifepoints by 200 over a short period of time, or by 400 lifepoints over a period if the player has completed the Seers Village Elite Tasks. The Saradomin godsword special attack will also heal you proportionately to the damage it deals.

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 40 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

 * Elidinis Statuette - this altar in Nardah will heal you and raise your total LP by 80, and will also fully refill your prayer. To use it, players will need to have completed Spirits of the Elid.
 * Guthix rest - Guthix rest, when drunk with 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.

 * Torva, Pernix and Virtus armour - Wearing a head-slot, body-slot and/or 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

 * 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.
 * 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.
 * 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.
