Mage tactics:
At beginning of battle, immediately run to the right (after swallowing some Greater potions of Strength/Dexterity/intelligence to boost Resistances)... if you have your creature summoned (which looks hilarious in the cutscene before that, since often he will walk before the 'camera') he should keep everyone busy.
Then throw a fireball through the chairs --> all paladins should be dead if it's maxed out. Then kill Divine with maxed out Firewall + Magic Blast... then torture Zandalor if you wish, he's pretty weak without his buddies.
If you can summon a demon too --> even better.
