The Heart Stone is an entity used to train Innervation.
Heart Stones have a chance of dropping when killing nearly any mob. The player will know when a Heart Stone dropped upon hearing a special sound.
Upon coming into contact with a Heart Stone, the player will gain some Innervation experience. The heart stone will disappear.
Depending on the player's Innervation level, collecting a Heart Stone can heal the player. The amounts of health the Heart Stone grants are given by this table:
|Innervation Level||Health healed|
|Level 1-7||0 (×0)|
|Level 8-14||1 (×0.5)|
|Level 15-36||2 (×1)|
|Level 37-69||3 (×1.5)|
|Level 70-100||4 (×2)|
