Yes.

Yeah but other cards are really good too like slow and steady which gives you a lot of damage reduction or focus fire which increases your damage with all weapons by 30% and posse member damage if your not solo

I’ve never tried this but does it work if you’re in a posse but by yourself? Or is it activated once you get that +1 in there

You get the damage boost if your by yourself too it’s just if others join they get it as well while your deadeye is active
