Hello henriquejr
Have you entered your talent in your hunting skills journal?
Not all animals have claws, wild boars or wolves have Talon, so it may well be that you took the wrong skill for it.
You can also attach a save game here so we can check if you think there's still an error. Game saves with Nehrim enabled can be found at:
...\Steamapps\common\Oblivion\Saves
we always need 2 files, a -.ess and a -.obse file,
(if possible no autosave or quicksave, but a manually saved one), put both in an archive and attach it to the post here.
oops
The translation here is rather contradictory, I normally use the German version and have just switched to English as a test.
There in the Hunting-Menue Claw and Talon is translated with Claws and Talon
but in the inventory with Claw and Claws (in the original german version this is "Klaue" and "Kralle")
Claws has been clearly confused here. sorry.
thanks for the hint
