Hit Points

Hit Points (also referred to as HP, Health or Life) represents one of the primary stats of units. It indicates how much damage a unit can be dealt before it is killed. This can be inspected in the user interface.

==Maximum Hit Points==
Combat differentiates between a unit's "Current HP" (or simply HP) and "Maximum HP". At the beginning of combat, the two values are equal for all your units. However, as units are dealt damage, their HP gets decreased, while their Maximum HP remains the same. This is especially relevant for effects that deal damage as a percent of a unit's Max HP (see Max HP Damage).
Notice that most effects here that increase a unit's HP refer to their maximum HP actually. An increase of HP itself is instead a form of replenishment which we talk about next.
==Replenishing HP==
While damage reduces a unit's HP, there are common effects that can increase a unit's HP.
* Life Regeneration is the most basic one, an innate ability for a unit to replenish life. It's also the slowest.
* Life Drain is another unit stat that allows a unit to replenish life when dealing damage (similar to what other games refer to as "Life Steal"). 
* Heal effects are in general of the highest impact. 
Notice that dead units (or figures) can't replenish their HP by any of these methods, and need to be revived.
==Multifigure Units==
Multifigure units (4-man and 9-man) split the total HP amongst the individual figures inside the unit. Regular sources of damage simply damage the entire unit, which then distributes it among its figures equally.
There are however specific effects that explicitly deal damage to multiple figures in a unit (please consult the unit pages referenced above for more information about this).
There are also spells that apply their damage to all figures inside the unit (splash damage), making them particularly potent against such units. These are in general area spells such as Implosion and Blizzard but are certainly not sufficiently documented at this point (either on this wiki or ingame).
The mechanic of figures dying is still subject to investigation. It seems that even in the absence of splash damage, multifigure units start losing figures after a certain threshold.

The primary means of improving one's units' HP is by leveling up and ranking up the units, with Artifacts and Holy Emblems also playing a major role.
