Slurp Bronze - Still Stagger?

I just decided to upgrade Slurp because of his bronze, but I played around with him for a bit and I didn’t notice those that got hit with his bronze were staggered. When he came out, I got nailed with it and was staggered repeatedly for the 10 seconds but that doesn’t seem the case now. I’ll keep him only semi-upgraded if it changed.

Can anyone confirm if his bronze still staggers over time?

It does. Maybe your opponent used an Ursus or mk2. I believe those were immune to staggers when certain conditions are met
