User blog comment:Xikhuang/Events that drop WHIS and ICARUS/@comment-28010522-20161130112556

Note: Aside Whis and Icarus, you might want to jot down events that drop Usher, Yemma, the Tree of Might (Ki +3 for I think 2 or 3 rounds, i forgot).

There's the event with Tree of Might awakening medals drop, too, which can be farmed, and traded for points at Baba's. But that's not support items.
