HugoPick #1 of 6 · S1
Best in slot by a wide margin and used by almost everyone: CRIT Rate, +45% CRIT DMG, and 25% DEF ignore for a few seconds after an EX Special Attack, Chain Attack or Ultimate deals Ice DMG, exactly his key skills.
Effect
False Personas
Increases CRIT DMG by 45%. When using an EX Special Attack, Chain Attack, or Ultimate to deal Ice DMG, the equipper gains the Absolute Zero Death Sentence effect for 3s. While Absolute Zero Death Sentence is active, the character ignores 25% of the enemy's DEF when landing a hit.

EllenPick #2 of 6 · S1
Neck and neck with her signature and sometimes ahead: it ignores 25% DEF for 3s after any Ice DMG EX Special Attack, Chain Attack or Ultimate hit, which is easy to maintain during Stun. The CRIT DMG is somewhat saturated on Ellen, but it's still very strong and easy to manage.
SeedPick #3 of 6 · S1
Nearly the same as Heartstring Nocturne with slightly less CRIT DMG, so marginally weaker.
Soldier 11Pick #3 of 6 · S1
Hugo's signature. Soldier 11 can't use its special buff, but the CRIT Rate main stat and big unconditional CRIT DMG still make it a strong pick.
Orphie & MagusPick #4 of 6 · S1
A slightly weaker stat stick than Heartstring Nocturne, with a bit less CRIT DMG and no Fire RES ignore.
CorinPick #4 of 6 · S1
Hugo's signature. It's a strong stat stick with plenty of CRIT Rate and CRIT DMG, only slightly behind Heartstring Nocturne.
Sigrid de L'AzurPick #6 of 6 · S1
Offers big CRIT DMG and DEF ignore when her EX Special Attack, Chain Attack or Ultimate deals Ice DMG, but its CRIT Rate main stat makes Sigrid overcap very easily. If you use it, cut CRIT Rate from your substats.
