something i discovered is that a dead Kog Maw who is about to explode isn't affected by Bards ult.
I was wondering if this is a bug or if it is intentional, as a dead Kog Maw is already immune...
Would be interesting if Sions passive is affected...
hope i could help.
Steps to recreate:
1. Play vs Kog Maw
2. Kill him
3. Ult him
