"Hint: Rare Grimoires for five different spells in one location:
At the Sinner's Corner save point/teleport/room and the four rooms immediately surrounding it is a phantom class enemy called the Dark Eye. After a Dark Eye is defeated it may drop a Grimoire for one of five different, rare, warlock class spells. Those spells are Solid Shock, Lightning Bolt, Fireball, Vulcan Lance, and Dark Chant. Note: that these Rare Grimoires are dropped very infrequently, and some time is needed to get them."
Jak dobrze pamiętam co niektóre z grimoirów były ciężkie do znalezienia,ze względu małych szans na wypadnięcie z potworów,te o których wspomniałeś nie wiem jak zdobyć,bo grałam bardzo dawno..
