Akujin inflicting Blind due to the darkness damage makes sense.
Kouenjin making a short explosion for (UL) makes sense.
Yukijin, inflicting Frostbite LV (UL) would be more neat.
Sanjin should only affect DEF in this case, and make sense.

All swords on UL*2% chance to have those effects triggering to match Raijin's possibility of crit (at 50%-75%)

Come on, boss. We want the other swords to be on Raijin's level of worth. Raijin has the only potential that 'can' be used in everything. (PvP and PvE)
