Luca Guide

Core combat tags for formation and element planning.

Luca (Pink Flash) is an R starter from Eldorana. R units cost little to field and keep exploration teams full while your roster grows. Available from premium gacha, pickup banners and the 12-SSR select pool (if SSR).

• Rarity — R; common pool unit for early story.
• Faction — Eldorana; see same-faction allies below for team-building ideas.
• Availability — Standard gacha pool.
• Tier snapshot — Luca is valued for Back Light coverage, not tier rank.
• Pull strategy — do not roll specifically; dupes come naturally.

Luca plays as a Back Light 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 Luca on the Back line of your 10-unit formation — their epithet "Pink Flash" reflects a Eldorana kit built for early-to-mid content.

• Formation slot — Back row; protect with tanks on Front.
• Element coverage — Light matches certain Calamity weaknesses; swap Luca when defense element charts demand it.
• Emblem loop — Passion self-charges on action; no battery required.
• Skill priority — level Luca's stance skills before off-element flex units; SR/R skills cap lower — invest only to floor breakpoints.
• Synergy — Eldorana allies listed below often share buff routes or aesthetic team themes.

Locate Luca inside Dot Abyss through the standard roster menus. Japanese players know the unit as ルカ — 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 Luca'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 Luca by understanding availability (Standard gacha pool) and spending materials only when the unit fits your 10-slot plan. SR/R units are replaceable; never outspend your SSR core for a bridge slot.

• 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 — excess SR/R dupes into the general altar; keep one copy for bond.
• Gear locks — lock good stat rolls before foddering duplicate equipment.
• Reroll caution — account deletion wipes all progress; finish rerolling before investing bond gifts.

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

Optimize Luca for launch-week defense and idle clears. Luca punches above R weight in Back slots until SSR coverage arrives.

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