Geist Ult hasn't been able to proc Mystic Reverb ever since they changed the damage type from spirit to true damage. Unsure whether or not this was intentional or not, regardless you can still imbue Reverb onto it.
Match ID is 39325998, but easy to replicate by just going to sandbox and imbueing reverb on Ult.
Times I ulted w/ Reverb was:
20:52 (note that Haze was given Guardian Ward not Divine Barrier)
27:30
What most likely caused this is the damage "type" Geist's ult was changed to, but I am unsure...
