CONSIDER IT — Sin is a Defender that both taunts and speeds up the squad's Burst cycle, worth considering if you lack a tank or need faster Burst rotation in multi-wave content; her Burst effect is less valuable against a single boss or low-target PvP.

Skill Investment Priority
General guideline: 4/4/4 → 7/4/7 → 10/4/10. Why: Skill 1 (taunt + HP copy) and Burst (AoE damage + enemy damage-taken buff) are her two core effects and should come first; Skill 2 only supports Burst gauge recharge, so it can wait.
Strengths & Weaknesses
Strengths
- Skill 1 both copies 15.03% HP from the highest-HP ally and taunts for 5 seconds, combining survival and aggro control in one skill.
- Skill 2 speeds up Burst Gauge recharge after Full Burst, helping the squad cycle through Burst windows faster.
- Her Burst raises damage taken by enemies in crowded fights, especially effective against waves of many small enemies.
Weaknesses
- Her AR normal-attack multiplier is only 13.65% ATK, below the general average, so she relies heavily on skills for damage.
- Skill 1's taunt only triggers when the last bullet in the magazine hits, requiring good reload timing.
- The Burst's enemy-damage-taken buff only applies with 5+ non-Nikke enemies present, useless against a single boss or a low-target 1v1 PvP fight.

Campaign
- Mob-Clear Team: Liter · Sin · Modernia · Noir · 1 flex Attacker. Words can Kill raises Damage Taken across the board once enemy count exceeds 4 — great for mob-heavy Campaign stages — plus AoE damage, and Full Stop's 5-sec taunt pulls fire off Modernia and Noir.

NoirArena/PvP
- Heavyweight Tank Team: Sin · Quency · 1 flex Supporter · Drake · Power. Full Stop's 5-sec taunt plus duplicating 15% HP from the highest-HP ally lets Sin soak the opening exchange; Hurry Up stacks effects with each burst use, so the longer the fight, the tankier Sin gets.
