A lot of ultros tanks seems incapable of understanding thisFor the merry-go-round Typhon, have Ulty's tank stack him with Typhon in the center, and have the imps follow the tank. Then, circle slowly along, grabbing the Aqua Breath stacks and avoiding AoEs as needed.
They wouldn't move/reposition instantly, so all the imps stacked in front of him, in range of Typhon's gust before he spins. Insta-massive damage/death to all 4 imps and a slow miserable wipe (people won't jump off when I told them to)
