Root Abyss Boss Mechanics

Vellum is hard to kill when you do more damage to him than your party does and he starts targeting you. Also harder when you have to buff to make sure he doesn't kill you, but surfaces when you're in the middle of buffing :/

So hard to dodge the stupid circle as a buccaneer when you can't get out of range if you're int he middle of the circle :C I don't die, but I can't land a hit on him. Not enough speed

A well timed Spiral Assault and then a CSB will allow you to negate the SKB and you might even be able to use a DS, OP or BB afterwards.

Plus, it's the fastest way to recharge energy for this battle, I think.
