While adventuring in Freshtovia, the module mentions that a certain Snacksmith (The equivalent of a Weaponsmith) can combine gemstones with weapons to make magical weapons, for a price, so the characters all jumped on this. The results I present below:

The Frosty Pairing Knife of Fang combined a sapphire and the paring knife Fang had on him.

Gnubnaver, despite his love for his battle whisk, decided to give over his ruby and a weaponized spoon.

Ko’ar asked to merge his Amathyst with his staff to get this item.

Galladin chose to have the diamond attach to his scimitar.

These items may be used and modified by you is you wish. Ironically enough, the player characters I have, nearly never use these magic weapons they got. Which is kind of disappointing, but it’s their choice.
