There are a bunch of odd quirks/bugs with Mystic Reverb, here are what I've found
Drifter: Rend will work on reverp if close enough to do Spirit Power
Victor: Reanimation cannot be imbued although I think it could as what seems to proc reverb is spirit damage.
Vyper: Lethal Venom being applied...
Lightning Scroll only works on ult damage. Drifter's Ult only does damage when you hit them while its active.
Doesnt work with his 2 right now, which is strange. Im not sure if thats what youre meaning.
Not sure if its a bug, but I dont think it should be allowed at all.
You can Teleport to minions with stalkers mark, meaning if you have a sightline on any "up" camps, you can just TP away.
Vexing Bolt
Not likely to happen, but the redirect will not reveal Shadow Weave
Spectral Assistant
Assistant will not shoot on use of Express Shot

Assistant teleport will not reveal Shadow Weave
Assistant is unaffected by Long...
Splitshot projectiles on shotgun heros builds up effects faster and will less falloff range.
Heros this affects: Abrams, Pocket, Calico, Mo & Krill, Shiv (Primary and Secondary Fire), Yamato (Primary Fire), Fathom,. Trapper

As the title says, if you get Djinn mark to be over 80 Damage for Mystic, or 165 for Tankbuster it doesn't proc either.
Doesn't work manually proccing Djinn's Mark, or letting it proc itself.
