Newbie having a hard time with RPM

For Invisibility, you can also consider the "Altered Traits" modifier for granting the Advantage.

Greater/Lesser is basically GM's call. It's going to be fuzzy. There's an upcoming book devoted to RPM that will probably have a lot more guidelines.

Invisibility fails this test for me.
