Emma: Tactical Upgrade is a Fire Nikke in the Supporter class, manufactured by Elysion. Stats and skill text below come straight from the game's data.
“Her outfit is infused with a special liquid that acts as an electronics jammer, which she can disperse into the air at will. This substance can interfere with communications or cause malfunctions in mechanical devices. Additionally, anything that comes into contact with the airborne particles is relayed back to Emma, effectively allowing her to use these particles as a wide-area detection ability.”

Should you pull?
CONSIDER. Emma: Tactical Upgrade is a rare tank-healer hybrid, well suited to lean squads that need a single versatile frontliner. Her Burst amplifying enemy damage taken is a meaningful team-wide bonus. However, Skill 2's crit-damage buff only reaches full value alongside Squad Absolute allies, and she has no significant active damage of her own — consider her for the tank/heal role rather than as a damage dealer.

Skill Investment Priority
Skill investment roadmap (Skill 1/Skill 2/Burst): 1/1/1 → 1/1/7 → 7/7/10 → 10/10/10. Why: Burst amplifies the entire Environment Setup effect from Skill 1 (doubling enemy damage taken, boosting healing potency), so it should be prioritized first; Skill 1 (healing + Taunt, the foundation of her tank/healer role) and Skill 2 (permanent crit-damage buff) can be leveled together afterward.
Strengths & Weaknesses
Strengths
- A rare tank (self-Taunt on enemy appearance) and healer (2.32% max HP per second, repeating every 30 seconds) combined in one unit.
- Burst amplifies Environment Setup, doubling enemy damage taken — directly boosting the whole team's damage output.
Weaknesses
- Skill 2's crit-damage buff only applies to allies from Squad Absolute, limiting value if the squad lacks that affiliation.
- No significant active damage output beyond buffs, relying entirely on teammates to finish the job.
