the reason you chooose a cleric is he heals, rogue for back row damage, warrior for taking damage and also for just doing a lotta damage, conjuror to summon buddies and also shoot bolts which is basically a mage so conjuror vs mage in my opinion conjuror would always win though i have not tested a mage at the level of my conjuror
if gargoyles didnt damage themselves when they atk they would be to overpowered and should be considerred leaders in the game lol i pwn 1k average with normal atk warrior and 1.2k with rogue sneak atk not too mention the 400 damage poison when he is going to atk
