Constitution

Constitution (also known as health, and formerly as Hitpoints or HP) is a skill that affects 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 or monster's life points reach zero.

The maximum number of life points a player may have without any armour or boosts is 40 times their Constitution level. Players begin with a Constitution level of 10 and thus 400 life points, and their life points are increased by 40 for every Constitution level gained. As such, a player with level 99 Constitution has 3960 life points.

Maximum life points can be increased by wearing armour. Without temporary boosts, the highest life points a player can have is 11,385, achieved at 99 Constitution by wearing full Primal armour.

Outside Daemonheim and minigames, 10,810 life points (13,052 with temporary boosts from rocktail soup and bonfires) may be reached by wearing Superior Tetsu/Death lotus/Sea singer equipment, Malevolent/Vengeful/Merciless kiteshields, Automaton gloves, Superior reefwalker's cape/Completionist cape, and Glacor boots. Free players may reach maximum of 7,785 life points from non-degradable defence level 50 equipment.

The number of life points a monster has varies between 1 and 480,000. Demon bosses have the most lifepoints of any monster (480,000), followed by Wahisietel (450,000), the Kalphite King (260,000) and Hati, Sköll and Vorago (250,000). The Party Demons had 200,000,000 lifepoints; however, it only appeared prior to the Evolution of Combat as a short event, and all use of lifepoints on the monster was exaggerated as a commemoration to Jagex having reached 200,000,000 registered accounts. The Zamorakian siege beast and Saradominist colossus had 212,500 lifepoints, but only appeared during the final week of the Battle of Lumbridge. Also of note is Vorago, who in hard mode has 2,250,000 lifepoints in total, although this is a combined total of his lifepoints in every phase, and not all at once.

The monsters with the lowest amount of life points are the rabbits in the Enchanted Valley, ogre shamans during the Watchtower Quest and the Evil creatures from the quests The Eyes of Glouphrie and The Path of Glouphrie with only 1 Life point. The Steel Titan has the highest amount of life points for a summoning familiar at 10,900 life points, followed by the Pack yak and Iron titan.



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 their Action bar to see their current maximum life points as well as how many they have remaining.

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 neutralise the poison, however.

For instance, if a player is hit by another player that poisons them, they would be hit for an initial amount of damage depending on the type of poison they were using. As time goes on the amount of damage is slowly reduced until it is gone. Players may cure the poison at any time with an antipoison or Super antipoison potion made using the Herblore skill. Super antiposions will give a player temporary immunity to any poison-based attack. This is especially useful 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 safe minigames, player-owned house, or certain quest areas, they will not lose any items on death, and will respawn in a designated location with all items retained.

If a player is in the Wilderness, upon death, they lose ALL of their items carried at the time. However, if a player in the Wilderness dies while the Protect Item prayer is on, they keep ONE item.

Respawning
When a player dies, they will respawn, meaning they will live again. Normally, the player will keep three of their items they were 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, a player receives Constitution experience upon the kill. 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.

Prayer cannot help train Constitution, however using the Rapid Heal or Rapid Renewal prayers, or the Soul Split Ancient 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 at the rate of roughly 1 life points per 1000 max life points every six seconds (rounded down) when not in combat.
 * Resting restores 1% of life points every 6 seconds.
 * Listening to a Musician restores 1% of life points every 3 seconds.
 * The prayer Rapid Heal doubles the rate at which life points naturally restore.
 * The prayer Rapid Renewal reduces the interval between natural healing to the users Life points from 6 seconds to 1.2 seconds.
 * The Regeneration aura doubles the rate at which life points naturally restore.
 * The Regen bracelet triples the rate at which life points naturally restore.
 * The lunar spell Dream restores life points at the rate of 5 times more than normal.
 * Entering a bank heals about 500 life points a second


 * The recovery rate for life points, in life points per minute, is given by adding natural regeneration (max life points divided by 1000. rounded down) to any regeneration increases (Rest has its own separate timer).

 * The maximum life point recovery rate without a familiar is 2510.5 a minute, using the best available equipment for maximum life points, having 99 constitution, wearing a regen bracelet, and using rapid renewal to cut the natural healing interval to a fifth of its normal time, and resting at the same time. For free to play the maximum life point regeneration, without using degrading equipment, is 918.5 life points a minute.


 * All restorations run on separate clocks. Resting/Listening to music/moving status on player is updated by one clock while the players natural regeneration is one a second clock. This second clock can be sped up using Rapid heal and Rapid renewal.


 * Eating food will recover life points. The full life points for a food will only be obtained if the player's constitution level is at least as high as the level of the food, which is generally the cooking level required to prepare the food (there are exceptions where the levels differ, such as the Tuna potato and Cavefish). For example, a Rocktail will heal 1860 life points if the player has a constitution level of 93 or higher. If the player's constitution level is 92, it will only heal 1472 life points, which is worse than a Shark which would give them 1600 life points.

 * Drinking Potions. Members have access to Saradomin Brews, which heal up to 500 of a player's total life points and adds it to their life points. This can exceed their limit.
 * Passive effects. Some weapons have passive effects that recover life points, such as the Enhanced excalibur and Saradomin Godsword. Additionally, the Guthan's set effect will occasionally heal a player by the amount they hit.
 * 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 other 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 10% 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.
 * Returning to a safe town. Life points are automatically recovered to maximum upon return to a safe town (like Edgeville) and using the bank.
 * 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 500, and will also fully refill your prayer. To use it, players will need to have completed Spirits of the Elid.


 * Bonfires - 1% to 5% of LP for 6 min to 60 min percent corresponding to your firemaking level, time corresponding with type of logs used. Note that this is a boost to LP high-water mark, the new higher level can be healed to by the usual means (food, banking, etc.).


 * The Thermal bath in Oo'glog boosts LP by around 433 above nominal maximum.


 * Rocktails, tiger sharks and rocktail soup can boost LP, in the case of soup by 15%.

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 (Now 4 in Evolution of Combat). These players were not able to use any Constitution abilities after the Evolution of Combat's release.
