Exploding Arrow Perk.

Is this a broken part of the game also?
There is an Nordmar Alchemist whom was kicked out of his Village (Fire or Wolf) for blowing up a shack.
He talks of needing ingredents and selling us some, yet after I got the ingredents he didn't offer me the Perk or the Arrows as Inventory items.
Since he is the Invernter of this seems he would be the Perk Merchant for this, well you would think.

Anyone know about this or figured it out?

To me he only sells fire arrows, I've never been able to get anything else out of him.

Here is the code for it if you need it
It_Perk_ExplosiveArrow
It_Recipe_ExplosiveArrow
ExplosiveArrow (Insert code)

Thanks for the tips I never got to the Recipe part.

I finally got my console working by unpacking my Pak files.

When I try to add a Perk like It_Perk_ExplosiveArrow all it does is Stack (like an inventory item0 with the current Greyed out Perk, i.e. I now have 2 Greyed out Exploding Arrow Perks.

Was thinking of trying to Insert a Charater Helper or Story Teller.

Does that happen for you as well or can you actually see a now Learned Perk, i.e. Red?
