I grinded for 1 mythical icy soul and here were my results
2x T3 (one was guaranteed)
9x T2
5800 SOW
4000 FC
350 rare souls
1000 3 star evo stones on each class in average
300 Skill shards
These are mostly rounded numbers
EDIT: Didn't and couldn't count the ironite but im sure it was lot. Also in some battles i got 15 SoT so some battles were free runs
