Thank for testing, Lina, but I still want to know the part about tech PA in general, on the element attack, but without potential unlock.

Says.. normal sword can't proc element down on boss. However, thunder sword can proc element down on boss now. (This potential 0)

So Talis with PA and thunder attack. Normally it can proc element down on boss already, does adding more element into it, making it proc element down even more often. (also potential 0 first, since I know that the proc rate on that skill is a constant number add)
