This value is actually represented by two values; the Maximum HP, and the current HP.
HP represents the most HP that creature can have. Normal healing cannot grant you more HP than this value, though it is possible to artificially raise this value, allowing a character more HP than they normally could have.
The initial HP value at level 1 depends on the character's Class, and the basic value will gradually increase by 5 per level, no matter what their class is.
Summoned creatures tend to have an HP value based on that of their summoner's level.
Sustaining damage in combat will reduce this value, and if it reaches 0, your character is Knocked Out. Your character will then have about 3 turns before they die. If they are damaged again within this duration they will also die. If combat is won before this time-limit is up, then that character will return to life, with 1 Current HP remaining. If combat is lost, then everyone will die (since everyone was Knocked Out)
- In combat, lost HP can be restored with certain spells, usually healing or life stealing.
- Outside of combat, lost HP is replenished over time (sitting will speed this up), or through consumable items (usually Baked items).
Players can often start a fight with a lower value if they have not properly healed from a previous fight.
Monsters will always start a fight with maximum Health, even if they sustained damage in a fight a few seconds before.
- "Health Point(s)" is often shortened to "HP", or referred to as "Life".
