Buy a New Weapon

This quest, which is given by Euphonia Teles in the Rook's Gambit once you complete Euphonia's Mission, requires that you seek out Four-Fingered Thad, Weapon Vendor. Simply talking to Thad will complete this quest.

If you plan on focusing on a particular weapon, you can purchase a weapon from Thad. However, you will not be able to sell this weapon later.
