Health

Health or health points (HP) is used to denote the life level for all creatures. When their health goes to zero, they die.

The maximum amount of health is determined by a combination of the player's base health (determined by class and level) and their Stamina. In addition, some items (both dropped and player-crafted) have +health stats. Finally, items can be enchanted to give additional increases to health.

Characters have an innate replenishment rate for both health and mana. The rate at which these two stats replenish is based on the Spirit attribute. There are also some Talents that can raise the replenishment rate for these stats independently. Health regeneration during combat is much reduced, but some health can be replenished instantly during combat using healing potions from alchemists or from various magical items. Out of combat, health regeneration can be increased somewhat by sitting down or increased significantly by eating various forms of food.

Base health
Base Health refers to how much health your character has before it is modified by talents, stamina, enchants, and other item effects. A few spells require a percentage of your base health to be cast, including Soulshatter (8%).

The value is dependent on class only, not on race.

Base health values at level 80
These are the correct values as of Patch 3.2.

How to calculate base health
As stated above, the base health is only dependent on your class. Each race will have the exact same base health. The calculation is quite simple.

Base Health = Max Health - Health From Stamina

Notes:
 * 1) Health From Stamina is given by hovering your mouse over the Stamina stat on your character screen. The part that says "Increases Health by XXXX" is how much Stamina is boosting your max health.
 * 2) Some talents boosts your max health by a flat percentage. You should remove the effect of this talent before doing the computation. So if it says you have 11000 health and you have +3% health then you would divide 11000 by 1.03 before you subracted the amount of Health it says you gain from Stamina.

Example : Kalium - 80 Human Warlock - Total Health 16505. Stamina Increases Health by 8860. 16505/1.03 (Fel Vitality) = 16024 16024 - 8860 = 7164 Base Health

Some of these values can be verified in-game with the few spells that use base health.

For example, at level 80, Bloodrage on a level 80 Warrior costs 16% of base health which in game shows up as 1299 health. 16% of 8121 is 1299.36 (the numbers all get rounded down).
