Sputnik — Review & Analysis
Sputnik is a 3-star Star unit built around single-target Mental DMG paired with control. Her core skill Orbital Inertia hits one enemy and adds bonus damage while her HP stays high, so she performs best while healthy. Her real strength is disruption: Silent Observation counters attackers by draining their Moxie to delay enemy Ultimates, while her Ultimate both deals damage and locks a target down with Disarmed and Silenced. Her natural role is an early-game sub-DPS and single-target denial pick.
- Her Ultimate deals Mental DMG and hard-locks a target with Disarmed + Silenced for 2 rounds, cutting off both enemy attacks and support skills.
- Silent Observation counters attackers to drain their Moxie, slowing the enemy's path to their Ultimate; at rank 3 it also grants herself Moxie.
- Her passive reduces DMG taken by 30% while under Counter, helping her stay healthy to keep her bonus-damage condition active.
- As a Star unit she is countered by Plant, so against Plant enemies she both loses damage and risks taking 30% extra damage.
- Orbital Inertia's bonus damage relies on staying at high HP, so she falls off the moment she is focused down; every skill is single-target, giving her no AoE clear.
Level her Ultimate first, since it is her strongest source of both damage and control and every Shaping node funnels more damage into it; next raise Orbital Inertia to round out her single-target output. For Psychubes, favor Attack/Crit Rate options to push her Mental DMG; if you want to keep her high-HP condition reliable, a survival-leaning Psychube helps her stay healthy and hold onto her bonus damage.
