Prototype Rancour Genshin Impact Guide ⇒ Best Builds & Tips

Prototype Rancour is a 4-star craftable sword in Genshin Impact, well-regarded for its ability to boost both offensive and defensive capabilities simultaneously. Designed with physical damage builds in mind, this weapon shines brightest in sustained combat scenarios where normal and charged attacks are frequently used.

Why Prototype Rancour Stands Out Among 4-Star Swords

Unlike event-exclusive weapons, Prototype Rancour has enduring appeal due to its reliable forgeability and consistent stat growth. Whether you’re a free-to-play adventurer or an intermediate player looking to boost a sword-wielding physical DPS, this weapon serves as a cornerstone for many builds.

Weapon Overview

Type: Sword
Rarity: ★★★★ (4-Star)
Base Attack at Level 90: 565
Secondary Stat: Physical DMG Bonus
Secondary Stat at Level 90: 34.5%
Passive Skill: Smashed Stone

Passive Ability: Smashed Stone

When you hit enemies with normal or charged attacks, ATK and DEF increase by 4% for 6 seconds. This effect can stack up to 4 times and is refreshed independently, meaning you can constantly maintain buffs during combat with minimal downtime. At Refinement Level 5, each stack becomes 8%, doubling the overall potential of this ability.

How to Obtain Prototype Rancour

Crafting: A Reliable Path for All Players

Prototype Rancour is permanently available through crafting, making it a favorite for players who want a dependable physical damage weapon outside of the Wish system.

Crafting Recipe:

Northlander Sword Billet ×1
White Iron Chunk ×50
Crystal Chunk ×50
Mora: 500 Mora (blacksmith fee)

You can craft this sword through any blacksmith in Mondstadt, Liyue, or Inazuma. One copy is also guaranteed as a reward after reaching Adventure Rank 10, making it one of the earliest 4-star weapons players acquire.

Best Characters to Equip with Prototype Rancour

Perfect Physical Damage Users and Support Hybrids

This weapon performs best on characters who primarily use normal and charged attacks. It becomes even more valuable with characters who benefit equally from both ATK and DEF boosts, enabling hybrid DPS/support roles.

Top Synergistic Characters:

Qiqi: Pairs well as her healing scales from ATK, and she benefits from sustained combat via Cryo-infused normal attacks.
Kaeya: A strong physical DPS pick when built with a physical damage focus.
Bennett: While generally used as a support, physical DPS Bennett can make good use of both ATK and DEF gains.
Jean: Her healing scales off ATK and she can serve as a field-sustaining hybrid.
Keqing (Physical Build): A non-electro Keqing built for raw normal attack damage can benefit significantly.
