Nina Guide

Core combat tags for formation and element planning.

Nina (Attendant of the Flash) is an SSR unit from Perdion, rated S on the launch tier list. Available from premium gacha, pickup banners and the 12-SSR select pool (if SSR).

• Rarity — SSR; highest pull rate tier at 3% base SSR.
• Faction — Perdion; see same-faction allies below for team-building ideas.
• Availability — Standard gacha pool.
• Tier snapshot — launch meta rates Nina at S.
• Pull strategy — reasonable select-pool or premium target.

Nina is an evasion-based Back attacker who converts successful dodges into Impact, then spends it on a devastating skill. She is self-sufficient as both generator and spender — the best permanent SSR for accounts that missed limited pickups.

• Dodge scaling — gear evasion and attack; Front tanks must hold aggro so Nina can dodge.
• Solo economy — works without Pico, though Pico still doubles her output.
• Select pool — available in tutorial redraw; realistic reroll target.
• Not with Wendy gen — pick one Front Impact source: Nina dodges OR Wendy hits, not both.

Locate Nina inside Dot Abyss through the standard roster menus. Japanese players know the unit as ニナ — search the character album if romanization differs.

• Formation screen — Frontline Base → Formation. Owned units show stance, element and emblem icons.
• Character album — greyed portrait means seen but not recruited; full color means owned.
• Gacha details — banner rate-up lists show whether the unit is currently featured.
• Wiki cross-ref — compare Nina's stats table on this page with the full character database.
• Tavern roster — recruited girls appear here for bond and shift assignment.

Protect your investment in Nina by understanding availability (Standard gacha pool) and spending materials only when the unit fits your 10-slot plan. SSR dupes and gear locks are expensive — confirm role before maxing.

• Availability lock-in — standard pool units can be duplicated over time.
• Account link — bind DMM after roster settles; unlinked saves are lost on device failure.
• Material funnel — feed SSR upgrade stones to Nina only after Front/Back cores are covered.
• Gear locks — lock good stat rolls before foddering duplicate equipment.
• Reroll caution — account deletion wipes all progress; finish rerolling before investing bond gifts.

Completing Nina's build means leveling skills, securing gear with the right stat rolls, and hitting bond milestones for permanent stat points. Nina is a Light / Back / Impact (衝撃) unit — every upgrade choice should reinforce that role.

Nina is S-tier because she solves Impact economy alone while delivering spender-tier damage — the F2P account pillar.

• Reroll friendly — in the 12 SSR select pool; aim here if limited banners fail.
• Defense flex — dodge procs scale with wave length like Electra's crit stacks.
• One-slot wonder — frees Assist for healer or Pico instead of a dedicated battery.
• Long-term — stays relevant when Wendy leaves the banner pool.
