Health Points represent the physical condition of a Character or Item. Depending on the nature of the game, when a character loses all of their Health Points they either are knocked out or killed. Items rarely need to keep track of their Health Points, but if they do, loss of all Health Points means the item breaks (this may be beyond repair).
How they are lostEdit
The most common way hit points are lost is from attacks. Hit points can also be lost from falling, crashing into things and many other sources.
