The strongest party I have made was in my DU playthrough, it was
DU 5 lvl shadow monk + 5 lvl rogue assassin + 2 lvl fighter, dual wielded, lot of invisibility + DU's invisibility cape, basically invisible every turn
Minthara vengeance paladin, no comments there it's a paladin
Laezel master of battle fighter - no comments needed as well
Shadowheart domain of life cleric with enjoyable Dark Justiciar skills
ancient paladin is better cause have anti magic aura
warrior or barbarian is still better than rouge or monk even with multiclassing
life cleric or light cleric is ok both are ridiculas with ring that give blessing and blade ward gloves both from act 1 for 2 turns
