MNK and Earthshaker.

[Aiurily]

Do you have a video example? It's hard to imagine being able to place them far away enough and not running into them while doing it, while simultaneously not blocking off the side of Bahamut.

Not saying you can't do this but I just don't know exactly how it'd be done efficiently.

mostly only applicable in phase 1. the distance between bahamut and the puddles is more than enough for p1's mechanics so it works out (since they disappear before the second earthshaker, and there aren't any pillars/tethers to worry about)
