Recently got Maschu +1 and wanted to post some of the things I've nailed down about Ukko's.
Hexa -> Ukko's = Light
Evis -> Ukko's = Frag and Ukko's -> Evis = Nothing
I think this nails down Ukko's SC properties are Light/Fragmentation. So, Breeze, Thunder, and Light gorgets should work for Ukko's.
The Slow seems to be static 1 min duration regardless of tp
100tp
300tp
When casting slow 1 you get the "no effect" message. Slow2 overwrites Ukko's slow.
Damage wise it's amazing and it looks so awesome!
No 2hr, No berserker drink/tonic, no cor, no brew(lol).
Parse of 13 Kukulkan fights we did the other night. Alihasan is 85 Masamune. Only 1 bard(marches), no Cor, but had stalwart's drink almost every fight.
Action Shot! The black circle kinda glitched because of the terrain =/ but still kinda cool. Note: Picture is huge so might have to right click and view it in another window to see all of it.
