You can dodge 100T with feather feet (he won't fall to the ground then and put your team in danger if your tank move), but even if it's working well (i'd say 90% of time), sometime it'll just miss.
I haven't saved my parse, but i'm pretty close to blm, brd are a bit away from me. on the fight, i just lose 3~4s when he does his 100T.

Actually we didn't do any speed run, so i'm enjoying as long as i can playing mnk on this mob (the most funny for me).
