Basic Attacks with a Bow
I have been shooting enemies as much as I can with my trusty bows, as I always do every test. For some reason during this test, the game seems to think that enemies are either stone pillars or sentient trees (not splinterlings though), because the arrows will hit the enemies, only to deal zero damage. I have even had a few situations where goblin trappers were shooting me and endlessly dealing no damage at all, while i stood there thinking they were a scrub, only to have it happen to me attacking the next goblin trapper XD. This can occur with any enemy at all, even Deer.
One thing i noticed though... when it would hit an enemy to deal zero damage, despite clearly hitting them... if there was an enemy behind them, it would sometimes deal damage to that enemy, instead.
