Thanks for trying it out!
1) Yes, for mastered lucky7 you would insert 150%, as each individual hit of the attack uses this number to compute the damage.
2) Shadow partner is currently not supported but wouldn't be too difficult to code in.
3) I have no idea why it's doing that lol.
4) I'm aware of the virus thing, but I'm not sure why it happens. If it makes you feel better, I can barely make this GUI, let alone a virus.
At some point, I'll take a look at the code to solve problem 3 since that seems quick and easy. Maaaayyyyyybe I'll do 2, but that one's a bit invovled atm.
