Im attempting to make Bound Apocalypse dual daggers and it says i need 1 bound apoc dagger and 1 bound angel slayer w/ haste. When i go to the luxury shop and buy and unidentified angel slayer i have to click it to make it bound. When i do that it automatically makes it have Crit dmg SA. How can i change this SA? is it random every angel slayer on what SA it gets?
