Frederica Guide

Core combat tags for formation and element planning.

Frederica (Curious Magitech Scientist) is an SSR unit from Eldorana, rated B 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 — Eldorana; see same-faction allies below for team-building ideas.
• Availability — Standard gacha pool.
• Tier snapshot — launch meta rates Frederica at B.
• Pull strategy — reasonable select-pool or premium target.

Frederica plays as a Back Neutral unit with the Passion (情熱) emblem. Back-line mage or shooter who self-charges Passion for consistent skill uptime. In auto-battle defense, slot Frederica on the Back line of your 10-unit formation — their epithet "Curious Magitech Scientist" reflects a Eldorana kit built for endgame content.

• Formation slot — Back row; protect with tanks on Front.
• Element coverage — Neutral matches certain Calamity weaknesses; swap Frederica when defense element charts demand it.
• Emblem loop — Passion self-charges on action; no battery required.
• Skill priority — level Frederica's stance skills before off-element flex units; SSR skill scaling defines clear speed.
• Synergy — Eldorana allies listed below often share buff routes or aesthetic team themes.

Locate Frederica inside Dot Abyss through the standard roster menus. Japanese players know the unit as フレデリカ — 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 Frederica'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 Frederica 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 Frederica 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 Frederica's build means leveling skills, securing gear with the right stat rolls, and hitting bond milestones for permanent stat points. Frederica is a Neutral / Back / Passion (情熱) unit — every upgrade choice should reinforce that role.

Optimize Frederica for launch-week defense and idle clears. Rated B on the tier list — a solid roster piece with clear strengths and bench timing.

• Defense template — slot Frederica on Back; 4–5 Back DPS.
• Emblem meta — Passion units run independently; great for flexible slots.
• Element swap — keep Frederica benched when Calamity element chart punishes Neutral.
• Upgrade order — invest after S-tier cores are online.
• Next steps — compare with tier list and formation guide.
