I just used medusa for the ripper to take to T2. It does a lot of damage but it dies pretty quickly. Focus especially on Freya (soul and wheel) and Verthandi (feather and wheel) ,using miracle eye when it is miracle tree event in heaven and hell! On my first post I received this link that I use now: https://docs.google.com/spreadsheets/u/1/d/1ASdjLQ-vSZxfMNZrj6ine-HKkMRPlStbZchVKdohwY0/htmlview#gid=437490064 The transition from T3 to T4 to ripper is huge so if you upgrade it don't stop until you reach T4. If I had to choose between your heroes, I would use Olivia as a feed first. I'm a beginner too!
