How to Get Thorn Blade in BG3? Explained

To get the Thorn Blade in Baldur’s Gate 3, you must visit Dammon at the Last Light Inn during Act 2. However, Dammon will only be available as a trader at the Inn if you defeated the goblins and goblin leaders in Act 1 to protect the Grove. If you let the goblin leaders live, or if for any reason you provoked a fight with the Druids in the Grove, then the Tieflings will die and Dammon with them.
Therefore, if Dammon is alive you will find him at the Last Light Inn. The Inn is located in the northern portion of the Shadow Cursed Lands and you’ll have to convince a cautious Jaheira you can be trusted before entering. Once you are past the guards, make your way to the stables where Dammon has set up a forge. You can purchase the Thorn Blade from him, as well as a number of other new gear pieces.
