So I gave my Kaden an unusual but seemingly effective build. I will probably only use him in AR and arena assault, so don't want to invest too much into him.
The build so far uses his prf weapon, shove, spd/Res link, drive Res, and drive speed. He shoves a Res tank, such as Fjorm or Eir, into range and gives them +15 spd/Res. This is perfect for Saias (soon to be +3 merged) who is my go to Res tank and with +Res blarserpent, DD6, light blessing, and Kaden can reach 77 resistance in enemy phase and have his awkward speed brought to 47 so can keep his B slot open for not QR3. For now, I'm using Fjorm since she's a bonus unit.
Anyway, I haven't filled out the special and A slot on Kaden yet and wondering what to put there. He's - atk/+spd. It's boring, but moonbow and fury seems the best?
