How to Upgrade Weapons in Wuthering Waves
To upgrade weapons inWuthering Waves, players need to navigate tothe Resonators menuin the Terminal. From there, they should access a character’s Weapons tab and select “Upgrade.” In the subsequent menu, they can level up the Resonator’s weapon using EXP points.
By clicking Auto-Select, empty slots are automatically filled based on the player’s inventory. However, it’s advisable to allocate upgrade materials primarily to their main weapons, as these resources are scarce.

Each level-up boosts the base stats of a weapon, and upon reaching the level cap, the weapon ascends. (Further details on weapon ascension can be found below.)
A faster route to access the weapon upgrade menu is through the Backpack. Players can choose a weapon from their inventory and directly access its ascension and tuning menu.

Weapon Ascension
Every 20 levels, an upgraded weapon must undergo ascension, breaking the level cap and enabling additional upgrades. Weapons can be ascended up to six times, with each ascension increasing the upgrade level cap by 10 to 20 levels.
Ascension materials can be obtained from overworld chestsor by completing main and side quests. Additionally, players can purchase ascension materials from the Weapon Crafting Store in Jinzhou. This shop is situated near the city hall, to the left of the Synthesizer.

List of primary ascension items:
Weapon ascension is linked to the player’s SOL3 Phase Level. With every 10 levels earned toward theirUnion Level Progression, their Phase Level increases by one. Therefore, to surpass the ascension cap, players need only to advance their Union Level.
Weapon Tuning
Tuning involves synthesizing a weapon’s duplicates. Each time a player obtains a copy of a weapon, they can merge it with the one they are already using. Tuning enhances the weapon’s Rank, thereby boosting its primary stat.
