STANDING STILL*
what is abnormal ? i don't see an issue here .You lose a shit ton of stam shooting at people while chasing them, and even bows way bellow your strenght will suck your stamina quite a lot.
I deleted my original post where I said "there is no such thing as a no stam bow" because I realized I hadn't tested it enough to make such a statement.
And after a lot more testing I'd like to report... running an INCREDIBLY low draw strength bow, I have yet to test anything that didn't consume a small amount of stam per shot. You can test this by just standing still and firing. Even for the lowest stam drain bows you'll see your stam bar dip temporarily before it quickly regens.
If "no stam" bows do exist, they are a bug. And if "no stam" actually just means "very low stam". Yes they do exist. And their damage per shot is garbage. Meaning their DPS also sucks given all bows have the same refire rate.
