|| wipechance = 0)

is assigning a value of 0 to the variable wipechance, I think you want to check if it is equal to zero.

|| wipechance == 0)

So lucy says it's a 1% chance for Guide Memory Blur, not 100% so you shouldn't use || wipechance == 0) either. Maybe if the value is 0 then set it to 1?

if(wipechance == 0) {
    wipechance = 1;
}
if(MakeRandomInt(0, 100) < wipechance)

or maybe it's a float value and it's coming back as 0 since wipechance is an int and it's really equal to 0.9999997
