Ahh I see what you mean (updated the OP to include the video link).
The Bug you are saying is:
- Malosi put his Status Effect on Drake Fong
- Drake Fong fired his special off, targetting Sif (and nearby) who had counter attack active
- Drake Fong died from the counter damage
- Blind Status Effect on Sif & nearby
I PERSONALLY am unsure if this is a bug or it is working as intended. I have passed it along to the SGG staff for their QA team to look into.
Essentially what has happened is essentially a “Order of Operations” thing.
- Drake fong fired his Damage
- Counter damage is calculated & reflected back at drake
- Blind applied
Because drake died from step 2, the De/Buff Blocker from Malosi was no longer in effect (status effects die with the hero) & as such the blind was applied.
