Do you know by any chance which sword you had equipped before you started the arachne quest? I probaly missed to include that weapon id in the script that makes you regain your weapon back after the quest.
im the type of player that hates losing any stats so i never change equipment. so im using the ceremonial blade, the same as ive used since i got it. and just to confirm it. youre not supposed to change classes after equiping a new weapon, right? since in the cave i think i tested a few weapons but changed back after, which is when i noticed that my skills were gone
I just finishes looking through the quest and could not find anything that would forcible changed the class in the Arachne Story. The ceremonial blade also has a listing id. So I am not quite sure what caused this.
Yes, the weapon class needs to be changed at the shop in town. Equipping any weapon not matching in the right class will result in no usable skills. That's how it should work.
The game saves your equipped weapon before any transformation happens. And returns it to you after changing back into human form. But it does not change the class you are having selected.
So maybe your saved weapon id was outdated and at the end of the quest the game gave you the previously saved weapon? That's the best I could come up with.
