Help please with "Fitting In"

I did it on one account but can’t remember how. I’ve got on skill gear and frag everyone, but I don’t seem to get it.

Suggestions appreciated.

It’s easy enough to do in PvE, though with the Napalm and AoE nerfs it’ll probably take a little longer. I just played on normal mode and didn’t engage until Frag Grenade was off cooldown. Bola’s Target Finder is nice for this challenge, if you have it.

Thanks. I’ll just keep trying. I did wonder about the AoE reductions.

Voids edge maybe adv so varelsis have enough hp.
Mob them rily taight and baang stack skill dmg if you can

Thank you, thank you, thank you. Followed your advice and just got it!
