This worked very nicely for bow, still a mystery how to do the same for all other shooting weapons.Look in buffs
example
"buffDrawBow1" and
"StaminaChangeOT" operation="perc_subtract" value="1.4"
Yeah I was looking at it, but since hold breath is a time limited stamina drain, and just aiming down the barrel drain stamina continuously, I am a little unsure. Guess I have to do some testing.Its probably "buffHoldBreathAiming1"
