Delta — Stats, Skills, Best Teams

Q: Should you pull?

CONSIDER. Delta is a permanent SR, no need to save pulls. Good for new players lacking a wide-taunt Defender; skip her if you already have a solid SSR Defender.

Q: Skill Investment Priority

1/1/1 (playable) → 4/4/4 → 4/4/7 (final). Prioritize the burst since it's the source of her taunt and decoy; Skill 1/2 are minor passives, so a modest even level is enough.

Review & Analysis

Delta is a Wind Defender manufactured by Elysion, wielding a Sniper Rifle — unusual since Defenders typically use close/mid-range weapons. Her Burst, Remember Me, creates a Decoy avatar carrying 91.68% of her max HP and Taunts all enemies for 10 seconds — a core aggro-pulling mechanic that lets teammates dodge incoming fire effectively. Skill 2 grants a strong DEF buff (51.42%) whenever she uses her Burst Skill, synergizing directly with her tank role. Skill 1 slightly boosts max HP on a Full Charge hit, adding a bit more overall durability.

Skill Investment Priority

Prioritize Burst (Decoy + Taunt on all enemies — her core tanking mechanic) → Skill 2 (large DEF buff on Burst use, direct synergy) → Skill 1 (minor max HP buff, supportive).

1/1/1 (playable) → 4/4/4 → 4/4/7 (final). Prioritize the burst since it's the source of her taunt and decoy; Skill 1/2 are minor passives, so a modest even level is enough.

Strengths & Weaknesses

Strengths

Her burst creates a decoy at 91.68% Max HP and taunts all enemies for 10 seconds, basically neutralizing one enemy attack wave.
Skill 1 self-buffs Max HP by 8.82% every time a Full Charge hits, so she gets tankier the longer the fight goes.
Skill 2 self-buffs DEF by 51.42% on using her Burst Skill, directly reinforcing her staying power.

Weaknesses

SR base stats (HP 307885 · ATK 8666) are low, and her ATK is nearly irrelevant given her pure tank role.
The decoy only lasts 10 seconds — once it expires, the team loses its shield instantly if the enemy wave isn't cleared yet.
Her Sniper Rifle normal attack needs a 1-second charge and only deals 65.95% ATK, contributing almost nothing to team damage.
