Health

Health, or HP, is the player's life in the game and is represented by hearts at the top of the screen (each heart represents 20 health). Each character starts with 100 maximum health, but that can be increased with Life Crystals up to 400.

Restoring
Lost health can be regained via consumption of the items listed below and/or via wearing a Band of Regeneration. Note that the effect will not exceed current maximum health, so you may end up restoring less health than the item is capable of.

All restoration items are affected by the cooldown (if not stated otherwise). The cooldown is a 13 seconds long period of time, which begins at the moment of consumption. During this period the player is not allowed to consume any more restoration items. This is there to prevent low-tier players from bypassing hazardous areas/enemies via "spamming" health.
