Thorn Blade

In Baldur’s Gate 3, the Thorn Blade is a weapon that can deal additional damage while you are using a spell that requires Concentration. With the Poison Synergy bonus you can deal an additional 1-4 points of Poison damage on melee attacks while you are concentrating. Additionally, this weapon also grants the user the ability to cast the Ensnaring Strike (Melee) spell once per Long Rest. Moreover, this spell requires Concentration, which will fulfill the requirements of the previous bonus.

Ensnaring Strike itself will summon thorny vines, dealing Weapon Damage and possibly Ensnaring your target. If the Ensnare is successful, your attacks against that enemy will also have Advantage on top of the additional Poison damage.

Furthermore, it’s possible to acquire two copies of the Thorn Blade. There is a chance that Dammon will sometimes restock this weapon. If you dual-wield two copies of the Thorn Blade, then the additional Poison damage will stack.

How to Get Thorn Blade in Baldur’s Gate 3

Baldur's Gate 3 Dammon at Last Light Inn location

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.
