 - This callback is called before the damage is actually applied to the NPC
 - Returning `false` will prevent the damage from being applied
-- The `damagerid` parameter will be `INVALID_PLAYER_ID` if damage is not caused by player
+- The `issuerid` parameter will be `INVALID_PLAYER_ID` if damage is not caused by player
 - Body parts use the same constants as `OnPlayerTakeDamage`
