I was using Dervish in AB and i have unlock the skill banishing strike. It is a great skill that if it hit a summoned creature, it deals 'Holy' Damage to i think is nearby foes. I tried the skill and it kills all the minion in 1 hit and brings the MM health down to < 25% health. If there are remaining minion(Flesh Golem due to higher level and more HP), you can use chilling vitory to finish off the MM.
These skill works on spirit as well, since they are summoned creature.
