Forum:SIREN Mercenary Question regarding Elemental Base Damage

Hello all. I had a question regarding the topic. I have a Lilith (level regardless). I have a Mercenary Mod equipped (+40% to SMG damage). I am using a hellfire (for easier example, lets say 100 base damage hellfire). Does the +40% damage from my class mod, along with smg proficiency, ect, add to the hellfire base damage? In another words, each hellfire bullet is doing 140 damage + the elemental fire damage? OR does SMG +X damage only effect non-elemental weapons?

I guess another pressing question would be, does a firefly mod increase the hellfire BASE bullet damage or ONLY the ensuing fire damage afterwards?

Thank you, help would be appreciated because ive been trying to see if the hellfires base bullet damage was being effected by the mercenary mod. I tried to test it, but too hard with all the damage numbers flying off :-P

Thanks for any help.
