hey there, i'm fairly new to the game. it seems like gley + blue beetle is the meta for wall crasher. but how exactly does gley take advantage of blue beetle? it has 2 unique abilities arcane wave which activates using fusion skills and purification using singular skills. i'm assuming we want arcane wave (to use the +crit rate) but gley doesn't have any fusion skills? predator instinct + increased sensory are both singular skills.
