Can't add skulls and shackles ap items
 

Hello!
I am trying to add the following two items from the skulls and shackles adventure path to my pathfinder hero:
- brine's sting
- eel skin armor

Via magic / add new magic item i cannot find them.
But they are visible within the editor. Even if i give them customs names, they want show up. Other items from the .user file are visible.

So maybe it's licence or configure hero (crtl + k) question?
How can i find out, which book contains these items?

Skulls & Shakles AP and Pirates of Inner Sea books are activated.

If I'm reading this right, you're trying these on the "Magic" tab? Brine's Sting is a weapon and needs added there, and the Eel Skin Armor is Armor, and is added under the Armor tab.

Yes ;(
After starting this thread, i figured it out, too. Stupid me.
I didn't see the buttons "New Magic" under Weapons and Armor ...

But i found the "source" button within the editor. It's the second last in the 3rd column in the center view of every item.

It's all good, we all have these moments
