for a spark team...

rosseta lead            spark on both SBB and LS

darvanshel              dmg mitigator

SGX                       crit buffer

diana/zelnite           BC/HC drop booster

michelle/ultor          atk buffer

not sure if u can make a crit squad if u dont have a unit that have LS that boost crit dmg like kira/maxwell/colt/mariudeth/vanberk

about raid if all you want is pass em and farm medals, the spark team should work fine..

but if you want to farm rare mat for crafting malice/buffer jewel, you will need a more specift squad for each boss
