If you have UW rune on your skill bar and you cast AotD on the live/S26 servers right now, it works as intended - sends some dudes out to do UW(u n.n) stuff.
If you then equip Fate’s Vow, it adds a normal (unruned) AotD effect in addition to the Unconventional Warfare skele when you manually cast AotD - UW. This is a bug
Fast forward to Season 27, now you have the game casting AotD - UW. This works as intended until you equip Fate’s Vow and trigger the existing bug, just automagically all over the screen.
And here is it doing the exact same thing on S26 live servers
The sanctified power isn’t the problem. It just draws attention to an existing bug.
