Evolution: Fast. With soulstones in hero Ch.2 and hero Ch.3 you can start collecting early on, and from two sources per day.

Cherry is a great unit in many ways, she packs a punch and has two stun skills. But her unique feature is that her 4:th skill can boost the energy regen of your entire team. Useful everywhere, but perhaps less so in a one-on-one situation (i.e. Event Battle). Opinion by AzakaZero
