This is my fastest Gilgamesh kill to date improving even further on the time I got with Nio FLB. And this is even considering the time I used to cast Yurius's skills. This team doesn't have any way to enable Grimnir's passive Wind ATK Aura, but it didn't matter much as I was always near cap at all times. The damage output of Grimnir is downright crazy and despite outputting such a huge amount of damage he still manages to support the entire team with his buffs. Gilgamesh literally couldn't do much for the entire fight as his debuffs were all controlled by Grimnir's veil or delayed by Raphael and Yurius. Maybe Ultima Staff is core in wind after all?
Going to try Ultima Spear next, but it may have to wait a few more hours as GW is upon us and I'll have to do coverage for that too.
