Echocalypse: Scarlet Covenant Stheno Pull Guide

Commit your summoning resources to acquire at least a base copy of Stheno if your squad lacks a dedicated limited damage dealer or relies primarily on standard-pool attackers. Stheno functions as a front-loaded burst carry designed to dismantle enemy formations early in combat while inflicting debuffs that expose survivors to follow-up attacks.

Stheno Skill Mechanics and Combat Strengths

Stheno centers on rapid burst damage and offensive disruption. To get maximum value from her kit, position her behind defensive units and pair her with energy support to trigger her rotation immediately.

Percentage-Based Burst Ultimate: Stheno fires an active skill at key enemy formations, delivering heavy percentage-based damage designed to bypass standard defensive mitigation layers.
Offensive Debuff Utility: Her strikes apply status penalties that reduce opposing damage output and amplify the damage targets take from subsequent friendly attacks.
Turn-One Rage Synergy: Her output spikes when paired with early Rage generation, enabling her to activate her skill rotation before opponents deploy shields, taunts, or defensive buffs.
Passive Stat Ramp: Stheno continuously builds Attack and Critical Rate across rounds, maintaining sustained offensive threat if an encounter extends past the opening rotation.

Star Breakthrough Milestones and Stopping Points

While a single copy unlocks her complete core functionality, duplicate shards provide distinct stat jumps and mechanical bonuses. Use these supported milestones to plan your draw budget:

Star Level	Breakthrough Focus	Recommended Target
0-Star (Base Copy)	Unlocks core skills and baseline burst rotation	Free-to-play and budget rosters needing a primary carry
3-Star	Enhances skill damage multipliers and initial Rage generation	Dedicated spenders looking for peak resource efficiency
5-Star	Maximize passive Critical Rate and Attack stat amplification	High-tier competitive PvP and top arena contenders

For accounts managing limited Iridim and Sachet supplies, stop after securing the 0-star base unit or reaching the 3-star milestone. Pushing to 5-star requires heavy resource reserves best reserved for competitive ladder rankings. Outside of star breakthroughs, invest in her designated Chimera and Vibe Arm equipment to scale her attack and critical damage stats.

Squad Building and Turn Order

Stheno needs energy acceleration and protection from early single-target burst to perform consistently. Structure her squad across three functional roles:

Frontline Vanguard: Deploy a durable frontline tank capable of taking initial hits while applying crowd control, team shields, or taunts. This protects Stheno in the backline from being sniped before she acts.
Speed-Tuned Buffers and Rage Batteries: Position offensive supports in the middle slots. Tune your team's speed so these units act directly before Stheno, filling her Rage gauge and applying attack buffs before she launches her ultimate.
Secondary Cleanup Attacker: Run a secondary damage dealer or debuffer to finish targets that survive Stheno's initial burst, preventing opposing healers from recovering lost health pools.

When to Pull or Skip

Evaluate your current account assets before spending your summoning stash on Stheno's limited banner:

Pull Stheno if: Your roster relies on standard-pool carries, struggles with damage checks in mid-game story chapters and Regression trials, or has accumulated resources specifically for a premium limited carry.
Skip or Hold if: You already heavily invested into recent limited burst attackers and lack the secondary framework—specifically reliable frontline tanks and turn-one Rage batteries—to enable her rotation properly.
