each shot takes 5% of your stamina
if your not in combat the cooldown between shots is very low, around 1 second. if you are incombat the cooldown gets increased to 3 seconds
if you get hit while shooting the hook it cancels the pull, while shooting the hook your also slowed down by alot
if you get hit while mid pull the velocity will cancel
