Kurumi — Stats, Skills, Best Teams

Q: Should you pull?

NOT A PRIORITY, best as an early-game stopgap. Being SR, her base stats are low; her main value is the wide Hacked debuff and damage-taken buff — useful before you have an SSR debuffer, but worth replacing once a better option is available.

Q: Skill Investment Priority

Suggested path: 1/1/1 (playable) → 4/1/7 → 7/4/10 → 10/7/10. Prioritize Skill 1 as the source of the Hacked debuff; level Burst alongside it to spread it wide; Skill 2 comes later since it needs 36 normal attacks during Full Burst to pay off.

Review & Analysis

Kurumi is an Iron Code Supporter made by Abnormal, belonging to the Café LycoReco squad; she is currently SR-only with no SSR listed in the data. Skill 1, Malicious Code Injection, applies a Hacked debuff to the target after 36 normal attacks (52.24% of final ATK per second for 5 seconds), and using her Burst spreads Hacked to all enemies. Skill 2, Payload Diffusion, adds a further 86.17% bonus damage to a Hacked target during Full Burst once 36 normal attacks are logged. Her Burst I, Defense Protocol Breakdown, raises all enemies' damage taken by 18.06% for 10 seconds, amplifying the whole team's damage. Being an SR, Kurumi is best used in early progression or as a cheap wide-debuff pick rather than a main damage source.

Skill Investment Priority

Prioritize Skill 1 (the source of the Hacked debuff, the combo's foundation) → Burst (spreads Hacked wide) → Skill 2 (bonus damage, needs a long normal-attack buildup).

Suggested path: 1/1/1 (playable) → 4/1/7 → 7/4/10 → 10/7/10. Prioritize Skill 1 as the source of the Hacked debuff; level Burst alongside it to spread it wide; Skill 2 comes later since it needs 36 normal attacks during Full Burst to pay off.
