Q: Should you pull?

Should you pull?PULL — Helm is a rare permanent Attacker that both boosts squad-wide crit and heals through her Burst, especially valuable if you're running a self-draining carry like Scarlet or lack a healer. Newer players can safely pull her since she is a permanent, non-limited character.

Q: Skill Investment Priority

General guideline: 4/4/4 → 7/4/7 → 10/4/10. Why: Skill 1 (squad-wide crit) and Burst (damage + heal) are her two core value drivers and should come first; Skill 2 only ramps up gradually, so it can wait.

Skill Investment Priority

Burst first — the big AoE hit plus team-wide damage-to-HP sustain. Skill 2 next for its permanent part-damage buff and Full Burst ATK boost. Skill 1 last, a shorter crit window.

General guideline: 4/4/4 → 7/4/7 → 10/4/10. Why: Skill 1 (squad-wide crit) and Burst (damage + heal) are her two core value drivers and should come first; Skill 2 only ramps up gradually, so it can wait.

Strengths & Weaknesses

Strengths

Skill 1 boosts squad-wide normal-attack Critical Rate by 14.64%, a useful AoE buff for any team needing stable crit.
Her Burst deals a massive 1237.5% ATK AoE hit within range and heals the squad for 54.45% of damage dealt as HP — finishing power plus sustain, especially good for self-draining carries.
Skill 2 permanently boosts damage to interruption parts, a stable stacking value with no RNG involved.

Weaknesses

Skill 1 only triggers when the last bullet in the magazine hits, requiring good reload timing.
Her Burst damage is huge but limited to attack range, not a true full-screen AoE like some other Attackers.
As a Sniper Rifle user she needs Charge Time to unlock her full normal-attack damage.
