Just found out, while you can’t use limacon AA while using Marching Fire, you can actually AA with pistol while using Marching if you don’t have limacon buff on.
You can also use crossbow AA however crossbow AA seems to override Marching Fire and causes Marching Fire to temporarily stop while in crossbow AA animation.
I think they should just make Limacon useable on marching fire and not give band-aid weapons that give high flat damage to makeup for it.
