Refresh dots and bane on Garuda to spread dots
Aim Garuda-egi at group of plumes have her AoE and and focus them down while personally making sure satin dies (if there's a group around Satin, might dot it up and spread via bane)
but yeah typically no problem. Don't recommend using tri or blizzard II. The mobs aren't close enough for either of them to be worth the speed or mana cost.
