Just slash atck Up +15

It has defense penetration 20

These dudes are trash it’s not slash up. it’s def piercing. U bypass 20 of ya opponent def so it’s +20 piercing and slash only if ya opponent has 20def

you're wrong too, thats not how it work. You dont bypass some1 with 20 def. 20 piercing mean 20% bypass. so if the opponent has 20 def, you will attack like he had 16 def (20% of 20 def = 4) and if you attack an opponent with 60 def, you will bypass 12 of his defense, like he had only 48 def.

lol
