30% Scrolls-For better or worse?

umm you're maths are flawed TS. if you roll a 100 sided die, and need 30 or less to land a scroll then it's: 30% to work and 70% to fail. then you have another dice roll if it lands on 30 or higher. this one is less than 50=use a slot, more than 50=bye bye item. that all happens in a split second and that's how it works

Why use a 2nd dice?

A 100 sided dice:
1-30 = Work
31 - 65 = Fail no break
66 - 100 = BOOOOM

Simple as that.
