So I changed my champion for you guys, but thought you might want a heads up:
She suffers from the same bug all the floating ball characters do that the circles don't intersect. To get a perfect hit you need to tap about .5 of a second after you tap her attack button. It's worth it. She's a little squishy but she steals power AND fury pretty much every turn if you can hit her perfect spot, & will sometimes do so on OK, good, or late.
Borrowing other ppls soldier Eddie (not having one of my own grrr) & using her with my gunner undead allied soldier & magus allied soldier reflect dude means this is the first day I have breezed thru the rift without pause.
What a difference having the right characters available & leveled makes...
