Powder burns aoe, how to stop FF?

[Zzz]

I have idea to make streetfighter with blunderbuss. Shooting powder burns, take self debuff distracted, and get free -50% recovery and +50% sneak dmg for 10 sec. This look very good in paper, but when i tested this i have some problem with aoe from modal ability. First time when i do FF i thought it have cone aoe, so i move my character a side with a tank. And he still take FF dmg! Next time i move my gunner face-to-face with enemy, and keep other character behind... and aoe still do FF.

I really confused with this, why this shot have 360* radius? How to counter this? I dont want FF.

 

And q about multiclass. I stuck in choose between monk and fighter, both are great - one have great dps, and other have hit+durability.

Can i take bloodied state from only turning wheel? Need at least 2 mortifications without upgrade, and wheel give percentage bonus to hp.

 

I see only this way- use powder burns(i think about 3 might for minimize FF dmg , lol), off modale, then twice morti and keep shooting.
