Granblue Fantasy Relink: Ferry and Uplift is a nice combo: Proud Proto Bahamut Run about 5 minutes

The amount of meter gained from her aerial loops is pretty insane with a maxed out uplift sigil. I could of probably spammed more supers at the start but it's still about a 5 minute run regardless. You can pretty much go from 0 to 100 in the span of the other 3 doing their SBAs it's pretty neat. Her barrage skill pretty much functions as soon as you cast it and can be rolled canceled for full pets which is neat. Also aerial loops doing more damage than onslaught feels like an oversight but at least you don't blow up your pets this way. You can pretty much do this anywhere on any boss and still gain SBA meter fast and links.
Would be cool if more people just randomly ran Linked Together sigils I'm just sayinggg.
