RAID: Shadow Legends Sand Devil 25 Fenax Speed Team Guide

To clear Sand Devil 25 in 14 seconds in RAID: Shadow Legends, replace slow attrition setups with a turn-one burst team centered on Fenax. By putting Al-Naemeh to Sleep before he takes a turn, stripping his defenses, and buffing Fenax's Attack, you can eliminate the boss in a single activation of Fenax's default skill before the boss triggers his wipe mechanics.

Why Fenax Bypasses the Stage 25 Damage Cap

Standard Sand Devil strategies rely on multi-turn survival engines, often using Godseeker Aniri to endure wipe cycles over two to three minutes. While reliable, these setups are slow. Traditional boss nukers like Coldheart, Royal Guard, and Gnut cannot speed up this stage because the game imposes a strict 10% maximum damage cap on skills that scale with Enemy MAX HP.

Fenax circumvents this limitation entirely because his damage scales exclusively from pure Attack:

High Multiplier: His default skill, Lead to the Slaughter, attacks twice with a 4.1x damage multiplier per hit, yielding an 8.2x total multiplier.
No Damage Cap: Because his hits scale on pure Attack rather than Enemy MAX HP, Fenax is not constrained by the 10% damage cap.
Sleep Synergy: When Al-Naemeh is under a Sleep debuff, his passive damage mitigation turns off and he receives 200% increased incoming damage. Fenax's two-hit A1 deals enough burst damage under this vulnerability window to deplete the boss's entire health bar.

Turn Order and Setup Execution

Executing a 14-second run requires every support skill to land before Fenax attacks. Attacking the boss normally breaks Sleep and triggers retaliation if the boss survives, so Fenax must deliver lethal damage immediately.

Turn Meter and Buffs: A fast booster applies Turn Meter fill and a 50% Increase Attack buff to the team.
Sleep Placement: A Sleep enabler inflicts Sleep on Al-Naemeh before the boss takes a turn, neutralizing his defenses.
Defense Reduction: A debuffer places a 60% Decrease Defense and 25% Weaken on the boss. This ability must not deal enough direct damage to wake the boss prematurely.
The Lethal Strike: Fenax uses Lead to the Slaughter. The first hit deals massive damage under the Sleep amplifier, and the second hit finishes the boss before he can wake up or counterattack.

Team Composition and Core Roles

Your team must cover four specific functions without taking extra turns or triggering redundant skill animations.

Role	Key Champions	Primary Function
Sleep Enabler	Siphi, Prince Kymar, Muckstalker	Applies Sleep before Al-Naemeh takes a turn
Debuff Specialist	Lydia the Deathsiren, Riho, Ghostborn	Places 60% Decrease DEF and 25% Weaken
Offensive Buffer	Arbiter, Cardiel, Shu-Zhen	Provides 50% Increase ATK and Turn Meter fill
Primary Finisher	Fenax	Casts A1 to eliminate the boss in two hits

If using an ally-attack champion such as Cardiel or Fahrakin the Fat, tune your team so all debuffs are applied to the boss before the ally attack triggers. Ensure your debuffers do not land weak hits against Al-Naemeh, as a missed Decrease Defense prevents Fenax from securing the kill. Void champions like Lydia eliminate affinity check risks.

Gear Priorities and Target Stats for Fenax

Because Al-Naemeh never takes an action during a successful run, you can ignore Fenax's HP, Defense, and Resistance. Build him as a dedicated glass cannon.

Recommended Artifact Sets

Savage and Lethal: Top priority. Stacking 25% defense ignore with the 60% Decrease Defense debuff ensures Fenax penetrates the boss's Stage 25 armor.
Cruel: Best secondary two-piece set to gain an extra 5% defense ignore and 15% Attack.
Instinct or Fatal: Suitable alternative sets if they provide superior offensive substats.

Stat Benchmarks

Critical Rate: 100% required. Missing a critical strike on either hit of his A1 results in a failed run.
Attack: 5,500 to 6,500+. Since his skill scales strictly from pure Attack, every additional point heavily amplifies damage during the Sleep window.
Critical Damage: 260% to 280% minimum, ideally reaching 300% or higher.
Speed: 175 to 195 Speed. Fenax must act after your buffers and debuffers, but before the boss moves.
Accuracy: 0 required. Fenax functions solely as a damage dealer; his debuffs are not used here.

Requirements and Failure Points

Switching to this burst setup trades broad utility for clear speed:

Single-Purpose Build: Fenax cannot survive wave content or general PvE encounters when built with zero defensive stats.
Accuracy Thresholds: Your Sleep champion and debuffer require high Accuracy (typically 350+ for Stage 25). If Sleep or Decrease Defense is resisted, the chain fails and the boss wipes the team.
Affinity Checks: Non-Void debuffers risk weak hits that prevent debuff placement. Use Void debuffers or skills that cannot be resisted to maintain consistent runs.
