I unfortunately don’t have the match ID, but I’ve run into these issues a few times each:
If you steal Victor’s ult as Sinclair right before dying, sometimes the ult does not activate and you die outright. Sinclair’s ult goes on cooldown as if they had stolen an ult and the timer expired for them to use it.
I’ve also had situations where if Sinclair has Cheat Death and steals Victor’s ult, sometimes both the ult and item proc at the same time, effectively wasting Cheat death.
I don’t believe Cursed Relic was involved in either of these scenarios. If it happens to me again in a game I will update this thread with a MatchID.
