Easiest way to get fusing stones

[Issaquah]

Any tips on how to best get fusing stones? Do I do chests or relic ruins quests, or something else?

Just keep playing through stages and the boss will drop them once in awhile. You can also get them from the silver chest. It's all based on your luck. By the way, for future questions, you should ask them in the thread dedicated to answering questions instead of making a new thread.
