Note: Do not max out Kain's lore (blood bar roughly the same length as lore bar and lore bar full). If this is done and the game is saved, Kain's blood bar will revert to absolutely nothing. If this happens, a simple jump will cause Kain to die. If you kill all available targets (including humans) throughout the game, you will achieve the same blood bar level as you would using the trick. If you do use this trick and are nearly maxed out, stop drinking blood and opening relics. Otherwise, you will lose all your hard work when you save.
