To unlock the full power of your roster in Genshin Impact, it is important to outfit your characters with the best weapons you can get your hands on. With the new Patch 3.0, there are even more new characters to collect, and each of them will require an appropriate new weapon. Luckily, Sumeru is a vast region and there you can find a variety of equipment for your roster. For example, you can craft a cool new 4-star polearm called Moonpiercer. If you’re wondering how to accomplish that, look no further. We’ll explain how to craft Moonpiercer in Genshin Impact and examine upgrades and stats of this new weapon.

How to get Moonpiercer polearm in Genshin Impact

To acquire the new 4-star polearm, Moonpiercer, you will have to find the proper diagram and forge it yourself. That is not as difficult as it might initially seem, as we’ll help you along with the process. But first things first — you need to get the forging diagram for Moonpiercer.

The diagram is sold by Aravinay, who is the vendor for forging blueprints. However, he can only be found in the dream realm version of Vanarana, which is called Mahavanaranapna. Vanarana is in the northwestern part of Sumeru, so now you know which way to embark on your journey.

Once you get to Aravinay, you will have to trade one Stories of You and Aranara to get the blueprint item, which is itself called Tale of the Moonlight. Stories of You and Aranara is a quest reward item that you will receive while adventuring in Sumeru.

After you have Tale of the Moonlight safely in your inventory, just learn the recipe and you’ll be ready for the next step of forging. That step is gathering all of the required materials. To be able to craft Moonpiercer, you will need:

  • 500 Mora1 Midlander Polearm Billet50 Crystal Chunks50 White Iron Chunks

Now that you have all of that, you’ll need to wait for the 10 seconds of forging to pass, and the blacksmith will present you with Moonpiercer, your brand new polearm. 

Moonpiercer stats

Moonpiercer is a 4-star weapon, meaning that it has some very good stats. The base ATK value is 44 at level 1 and maxes out at a whopping 565 at level 90. Moonpiercer’s secondary stat is Elemental Mastery which enhances Elemental Reaction. It starts out at 24 at level 1 and gets up to a max of 110 at level 90.

Along with all those stats, Moonpiercer has its own refinement power called Stillwood Moonshadow, with the effect:

  • After triggering Burning, Quicken, Aggravate, Spread, Bloom, Hyperbloom, or Burgeon, a Leaf of Revival will be created around the character for a maximum of 10s. When picked up, the Leaf will grant the character 16% ATK for 12s. Only 1 Leaf can be generated this way every 20s. This effect can still be triggered if the character is not on the field.

With every new refinement level, the bonus ATK increase of Stillwood Moonshadow grows in increments of 4%. This means that Moonpiercer’s ATK increase bonus can be refined from level 1 to level 5, amounting to:

16% > 20% > 24% > 28% > 32%

Moonpiercer Ascension

Moonpiercer is a weapon with a total of six ascension levels. As always, each ascension level requires specific materials and a payment of Mora to complete. To ascend from level 0 to 1, you need:

If you are flush with resources and want to complete Moonpiercer’s ascension all at once, or you simply want to know what the total amount of resources needed would be, that means that you will have to farm up in total:

  • 150,000 Mora3x Oasis Garden’s Reminiscence9x Oasis Garden’s Kindness9x Oasis Garden’s Mourning4x Oasis Garden’s Truth15x Chaos Storage18x Chaos Module27x Chaos Bolt10x Recruit’s Insignia15x Sergeant’s Insignia18x Lieutenant’s Insignia
