Is the kuko working?

I remember from long ago that the explosion arrow on the kuko didn’t do damage but was only visual. Was this bug ever fixed?

using raven claw - same stat - and it works

I think the issue is with merc.

That’s how I was thinking of using it. I used to like the idea of a rouge merc getting AoE damage while I tanked things. Then I heard it didn’t work.

So I’m getting the idea that it works for players but if I put it on a Rouge it won’t carry the AoE?

Fire arrow or magic arrow in item dont work in mercenary.
I know, show the visual animation, but no damage.

Unless they changed it again it should only shoot exploding arrows on basic attacks.
So if you use normal attack it will shoot a lvl 7 Exploding Arrow (not sure if synenergies are counted).
If you use multishot, strafe, guided arrow or any other Skill it will use that skill on your arrow and not the level 7 exploding arrow.
On mercs it never shoot the exploding arrow from the weapon.
This counts for all weapons with Fires Explosive Arrows or Bolts and Fires Magic Arrows as far as I know.
