Solve the Masterwork Weapon Mystery overview

Solve the Masterwork Weapon Mystery is an Act One side quest about recovering a blacksmith’s lost instructions and completing his Sussur weapon design.

The quest begins in the Blighted Village, where the player can discover Highcliff’s Journal or the relevant blueprints. These materials explain that Highcliff left behind a method for forging a special weapon with Sussur Bark, turning an abandoned blacksmithing mystery into a practical crafting objective. Finding either starting item provides the trail the quest follows, although the supplied sources do not establish whether one item is required before the other can be found.

The central expedition takes the party away from the Blighted Village and into the Underdark. There, the objective is to locate and harvest rare Sussur Tree Bark. The bark is the distinctive ingredient in the design, so the quest is not completed simply by reading Highcliff’s notes; the party must bring the material back to the village before the forge can be used.

Once the bark is secured, return to the Blighted Village and use the furnace and bellows to finish the work. The player must combine the Sussur Bark with a common version of one eligible weapon: a Greatsword, Sickle, or Dagger. The result is one of three rare magic weapons, and each finished weapon can silence a target when it lands a successful hit.

Walkthrough

1. 01

   Find Highcliff’s Journal or the blueprints.

   Search the Blighted Village for Highcliff’s materials

   Begin in the Blighted Village and look for Highcliff’s Journal or the blueprints connected with the abandoned blacksmith. Reading or finding one of these materials establishes the weapon mystery and points the party toward the Sussur-based crafting process.

   Location: Blighted Village

   TipKeep both the clue and the intended weapon choice in mind before leaving the village; the final craft requires a common weapon of a matching type.

2. 02

   Understand Highcliff’s Sussur weapon design.

   Read the instructions and identify the required material

   The journal or blueprints describe a special weapon made with Sussur Bark and provide the reason the quest continues beyond the village. Treat the notes as the crafting plan: the party still needs to obtain the rare bark before the furnace can produce the finished weapon.

   Location: Blighted Village

3. 03

   Locate the source of Sussur Tree Bark.

   Travel to the Underdark

   Follow the quest’s lead into the Underdark, the region identified as the source of the rare ingredient. The supplied material does not specify a single route, entrance, enemy encounter, or sub-area, so focus on reaching the region rather than relying on an undocumented path.

   Location: Underdark

   Watch outDo not return to the forge expecting completion before collecting the bark; the supplied quest facts identify it as a required part of the recipe.

4. 04

   Obtain Sussur Tree Bark.

   Locate and harvest Sussur Tree Bark

   Search the Underdark for the Sussur Tree and harvest its bark once the party reaches it. This is the resource-gathering stage of the quest, and the bark must be kept available for the return trip to the Blighted Village.

   Location: Underdark

   TipCheck that the bark has been collected before leaving the Underdark. The sources do not establish whether additional bark can be obtained, so avoid treating it as a disposable ingredient.

5. 05

   Prepare one common Greatsword, Sickle, or Dagger.

   Bring a common eligible weapon to the forge

   Before completing the craft, make sure the party has a common version of the weapon type you want to enhance: a Greatsword, Sickle, or Dagger. The choice is consequential for the reward because the bark combines with one weapon and produces the corresponding Sussur variant.

   Location: Blighted Village

   Watch outThe supplied facts support one of three weapon outcomes, not all three from one crafting sequence. Choose the base weapon deliberately.

6. 06

   Forge the chosen weapon.

   Use the furnace and bellows

   Return to the Blighted Village and use the blacksmithing equipment identified by the quest: the furnace and bellows. Combine the Sussur Bark with the common weapon you selected to complete the masterwork and receive the matching enchanted Sussur weapon.

   Location: Blighted Village

   Checkpoint
7. 07

   Claim the completed Sussur Greatsword, Sussur Sickle, or Sussur Dagger.

   Equip or store the finished Sussur weapon

   After the craft, verify which Sussur weapon was produced and decide who should use it. Its defining property is the ability to silence targets on a successful hit, while the supplied sources do not provide additional numerical statistics or class restrictions.

   Location: Blighted Village

   TipUse the weapon type that matches the character you expect to make successful attacks most reliably.

Mission mechanics

This quest uses a simple discovery-to-crafting structure. The player first finds Highcliff’s Journal or the blueprints in the Blighted Village, then follows the instructions to the Underdark for Sussur Tree Bark. The quest therefore depends on moving between two regions rather than completing every step at the starting site.

The final item is determined by the common weapon supplied for the combination. A common Greatsword produces a Sussur Greatsword, a common Sickle produces a Sussur Sickle, and a common Dagger produces a Sussur Dagger. The supplied sources do not establish that the choice can be reversed after forging, so select the base weapon with care.

All three outcomes share the same central identity: they are rare magic weapons with the ability to silence targets when a hit succeeds. No damage values, attack modifiers, duration, saving throw, or other numerical details are included in the supplied material, so those properties should not be inferred from this guide.
