Frostscourge Stalker Echo Ability
The Echo Ability of the Frostscourge Stalker summons a spectral projection of the Stalker to strike nearby enemies, dealing 129.60% Glacio DMG. This value corresponds to a 5★ rarity Frostscourge Stalker Echo. The summoned attack delivers a quick burst of elemental damage, making it a useful utility Echo for applying Glacio-based effects or triggering elemental reactions. The ability has a cooldown of 8 seconds, allowing for frequent use in combat rotations, especially for characters that benefit from consistent elemental application or short-burst Echo skills.
Possible Sonata Effects
The Frostscourge Stalker Echo can contribute to one of two possible Sonata Effects depending on its assigned attribute and set composition: Midnight Veil or Eternal Radiance.

With the Midnight Veil Sonata Effect, equipping a 2-piece set grants a +10% Havoc DMG bonus, enhancing the damage of characters who specialize in the Havoc element. When a 5-piece set is equipped, triggering an Outro Skill causes an additional 480% Havoc DMG to nearby enemies. This bonus damage is treated as Outro Skill damage and additionally provides the incoming Resonator with a 15% Havoc DMG Bonus for 15 seconds, enhancing their elemental output immediately after the rotation.

Alternatively, the Eternal Radiance set focuses on boosting Spectro-based Resonators. The 2-piece bonus offers +10% Spectro DMG, supporting consistent elemental scaling. The 5-piece bonus increases Crit Rate by 20% for 15 seconds upon inflicting Spectro Frazzle on enemies. Once a target accumulates 10 stacks of Spectro Frazzle, the attacker gains a 15% Spectro DMG Bonus for 15 seconds, greatly amplifying Spectro-oriented damage windows.
These Sonata Effects make the Frostscourge Stalker a versatile option for both Havoc and Spectro builds, depending on how it fits within a full Echo set.
Acquisition & Farming

The Frostscourge Stalker Echo can be acquired by defeating Frostscourge Stalker enemies found in the overworld. These elite enemies are typically encountered in fixed locations and can be tracked using the in-game Guidebook, which marks their position on the map once discovered. After defeating a Frostscourge Stalker, there is a chance for the Echo to drop, with higher rarity versions appearing at higher SOL3 Phase and Union Level thresholds. Additionally, Tacet Field Cleanups also serve as a possible source for obtaining the Frostscourge Stalker Echo, offering players another reliable method to farm Echoes through structured combat challenges. Echo drop rates and rarity will depend on the difficulty and your current progression level.
Suggested Characters
The Frostscourge Stalker Echo is a versatile 1-Cost Echo that deals Glacio DMG and has a short cooldown of 8 seconds, making it an effective and flexible choice for characters who rely on frequent Echo activations, elemental triggering, or low-cost Echo rotations.
