How helpful is Gemini in raids?

Would it be worth leveling her up for raids? Just wondering since I keep up with unique raids with parat 24, rhino 25, troodoboa 22, and sometimes my Thor 23.
Also what would be the easiest apex raid to get ready for?


All apexes from cera-hydra have atleast a 9 turn strat that uses avg 1500-1600 dmg gems. Should also work for 12 turn trebax strats. For uniques pho and parat seem to work with unboosted gems

Really big gems can also be used inplace of maxima in 6 turn mortems
