Stuf not working

playing with sorcerer i can tell you warmth isnt working, im casting firewalls when no one is around and loosing HP, same with every spell that cost mana is costing me HP..runic effects arent working i can post about them in detail IF im taken seriously. in some boss fights some effects immediatly kill me despite me having skills that are supose to prevent death on a cooldown dont actually know if theyr are really suposed to null them wich kinda makes certain fights like bartoc unfair if you not using teleport or jump skills… currently on the lookout for more issues since game wont be refunded…
