Moonpiercer is a four-star polearm in Genshin Impact that is part of Sumeru’s series of craftable weapons. Being fully compatible with free play, this weapon is a cheap option for support characters who primarily trigger Dendro’s elemental reactions on his team, so careful team composition is required for the weapon to shine.
How to get Moonpiercer in Genshin Impact
Moonpiercer is a craftable weapon, so it cannot be obtained by pulling any banner. Instead, you have to play through Sumeru’s Aranyaka quest chain to get quest items called Stories of You and the Aranara. Then talk to Aravinay in the Vanarana dream to exchange them for Forging Blueprints, including the moonlight talewhich is used to make Moonpiercer.
Learn the Blueprint by using it from your Inventory, then head to any blacksmith to forge it with the following materials:
- x1 Midlander Claymore billet
- Crystal Shard x50
- x50 White Iron Cunk
- x500 Blackberry
It only takes 10 seconds to get this polearm and you can craft as many as you want for Refinements.

Who can use Moonpiercer in Genshin Impact
Moonpiercer was created for support characters whose job it is to activate dendro Elemental Reactions, so you need to build the right team and keep your rotations in mind to make good use of your passive. When the wearer activates elemental reactions, a rebirth blade will be summoned. Whoever picks it up (not necessarily the wielder) will gain a huge attack boost, further increasing the weapon’s support capabilities.
However, despite the army of polearm users in the game, only a few can make full use of Moonpiercer:
