RAID: Shadow Legends: Fenax Sand Devil One-Shot Build

To one-shot the Sand Devil's Necropolis boss in RAID: Shadow Legends using the Epic Champion Fenax, gear him purely for offensive damage so his A1 ability ("Smite") finishes the boss in a single turn. Because his A1 prevents targets from being revived, a successful single hit bypasses the boss's revive mechanics entirely.

Stat Requirements and Gear Sets

A successful one-shot setup sacrifices survivability and speed for raw offensive output. Prioritize high-end damage sets that ignore enemy defense.

Gear Set	Role & Benefit
Savage or Lethal	Primary four-piece requirement. Provides defense-ignore mechanics essential for breaking high boss defense.
Cruel	Optional two-piece supplement. Adds Attack % and an extra layer of defense ignore.

Target Stats

Critical Rate: Exactly 100%. Missing a critical hit results in an immediate run failure.
Critical Damage: Aim for 250% or higher. High Attack without sufficient Critical Damage will leave the boss alive.
Attack %: Primary scaling stat on gear pieces such as chestplate and gauntlets to maximize raw damage.
Speed: Secondary priority. Focus investment on burst power rather than turn frequency.

Required Masteries and Team Support

Fenax cannot reach the one-shot threshold on gear alone. He requires specific mastery support and team debuffs applied before his turn.

Mastery Requirement

Helmsmasher: This Tier 6 Offense mastery is mandatory. Its 25% defense-ignore chance provides the necessary damage spike to clear the boss's total health pool.

Required Support Champions

Before Fenax acts, your team must set up the target by applying three essential battle conditions:

Increase Attack (buff on Fenax)
Decrease Defense (debuff on Sand Devil)
Weaken (debuff on Sand Devil)

Without all three effects active, Fenax will leave the boss with remaining health, forfeiting the one-shot bypass.

Limitations and Next Action

This build hyper-specializes Fenax. A build configured exclusively for Sand Devil one-shots generally lacks the survivability or speed required for general content like Arena or Hydra.

Next Action: Before committing high-tier Savage or Lethal sets permanently, test Fenax's total damage in lower stages of the Sand Devil's Necropolis to verify that your team setup consistently lands all required debuffs before Fenax uses his A1.
