This is what the description of carve owl says
“Carve an owl sculpture to protect yourself from the attacks of enemies in front of you”. It has a very similar description as with quarrel shooters Deply Pavise. Every point put it in this skill increases the “number of blocks”.
Now first of all, owl doesn’t actually “protect” you and second, it doesn’t actually “block”. What’s the point of having the number of blocks in the description when all it actually does is the number of hits it needs to take it down.
My suggestion is to atleast make them true to their description and give owls an actual block function. That way they won’t bounce around and be useless against 95% of the bosses in-game without having to be all tacticy and lure them near a wall or scream at your tanker to not aggro in the middle of the map.
