The shot time can be reduced further with extra levels of Fin or SoG, but no lower than 0.1 sec / dualshot.
Hmm, for some reason in one of my last AoMr runs I had 0.09 fire speed displayed :| .
Does an F3 tristar blaster really fire 9 shots? Are they just invisible due to overlapping the normal ones?
Yes, but I'm not sure how does it stack with Scout's intrinsic speed boost. It's either 130% base or 120%*110% base (that is 132% effective speed).
In watching Game Hunter's tutorials, it seems that monsters want to gather in the center of the maps, but I am not noticing this behavior at all in 0.9.9.6.
