I had a test at the end of the game for the guardians....
Fill all bottles with a strong VI Potion, so that every (in my case 2 characters) characters has 8-10 potions.
Fight with the "Blue Steel" and the "Vorax".....that was my quest against the guardians.....
Or do you mean the 4 guardians in the cellar of the forrest, near the "Nines World door" ?
I also killed all 4, how ? Go to a small corner where the iron door is, then i used the "Magic Back Spell" and second i sent many "Fire Minions" into the room, they killed them for me
