Forging the Moonpiercer: A Traveler's Guide to Sumeru's Craftable Polearm

In the verdant, dream-laden forests of Sumeru, a unique weapon awaits those willing to delve into its ancient secrets. The Moonpiercer, a craftable polearm introduced in Genshin Impact's monumental 3.0 update, remains a sought-after armament for its distinctive powers tied to the Dendro element. Its passive ability, Stillwood Moonshadow, functions much like the fiery pepper dropped by Guoba, summoning a Leaf of Revival whenever the wielder triggers a Dendro-based Elemental Reaction such as Quicken, Aggravate, or Bloom. Picking up this leaf grants a significant ATK boost for 12 seconds, making the Moonpiercer a strategic tool for amplifying team damage. With an Elemental Mastery sub-stat, it shines when placed in the hands of off-field support or sub-DPS characters like Xiangling or Thoma, who can trigger reactions and let the main damage dealer collect the empowering leaf.

The Key to Crafting: Stories of You and the Aranara

Unlike weapons found in chests or wishes, the Moonpiercer's path to creation is one of perseverance and story. To forge it, one must first obtain its schematic, the Tale of the Moonlight Forging Blueprint. This diagram is not sold for Mora or found on a merchant's shelf; it is purchased with a special, story-bound currency: Stories of You and the Aranara. These are precious Quest Items, each one a testament to the Traveler's deeds and bonds formed within Sumeru's woods.

Acquiring these stories requires completing specific chapters of the sprawling Aranyaka questline. As of 2026, the following endeavors each grant one stack of this rare currency:

• Completing the World Quest "The World of Aranara in Aranyaka: Part II - Dream Nursery."

• Defeating the formidable Abyss Lector during the World Quest "Vimana Agama."

• Successfully repairing the Varuna Contraption in the World Quest "Varuna Gatha." 🛠️

• Seeing through the World Quest "Agnihotra Sutra" to its conclusion.

• The pivotal act of rescuing Rana in the World Quest "Aranyaka: Part IV - In the End, the Forest Will Remember."

Each completed objective weaves another thread into the tapestry of the Traveler's journey, with the Stories of You and the Aranara serving as tangible proof of these adventures.

Journey to the Dreamland Merchant

With at least one Story of You and the Aranara in hand, the next destination is a realm hidden within reality. The blueprint vendor resides not in the waking world, but in the Dreamland version of Vanarana. To access this ethereal marketplace, one must first complete "Aranyaka: Part II - Dream Nursery," which unlocks the ability to enter this dreamscape.

The process is magical:

1. Travel to the Silapna in Vanarana.

2. Play the Vintage Lyre received during the quest in front of it.

3. The world will shift, transporting you to the lush, glowing Dreamland.

Once there, head west towards the majestic Tree of Dreams. There, you will find Aravinay, a gentle Aranara shopkeeper. This NPC offers a selection of Sumeru's weapon forging blueprints, exchanging them solely for the Stories you've collected. Approach Aravinay, browse his wares, and purchase the Tale of the Moonlight Forging Blueprint to begin the final phase of your quest.

Gathering Materials and Final Forging

Holding the blueprint is only half the battle. To finally bring the Moonpiercer to life, a visit to any blacksmith in Teyvat is required, along with the following materials:

Material	Quantity	Primary Source
Midlander Polearm Billet	x1	Weekly Boss rewards, Souvenir Shops, or special event exchanges.
Crystal Chunk	x50	Mined from cliffs and mountainous areas across Teyvat.
White Iron Chunk	x50	Commonly found in mines, near cliffs, and throughout Mondstadt and Liyue.

The Midlander Polearm Billet is the rarest component, often requiring patience and challenge. Once all items are assembled, proceed to a forge, select the Moonpiercer from the crafting menu, and witness the birth of a weapon born from Sumeru's dreams. Its elegant form, now a reality, is ready to channel the power of Dendro reactions and cast its moonglow upon the battlefield. For Travelers who have walked the path of the Aranara, the Moonpiercer stands not just as a powerful tool, but as a lasting symbol of the friendships forged and the forests remembered.
