Marina Guide

Core combat tags for formation and element planning.

Marina — Travelling Merchant of Everything — is an SR bridge unit from Eldorana. SR characters fill your early 10-slot formation cheaply and several remain useful after SSR cores arrive. Never appears in the tutorial redraw pool — only from standard or featured banners after chapter 1.

• Rarity — SR; solid 12% SR rate filler.
• Faction — Eldorana; see same-faction allies below for team-building ideas.
• Availability — Not in tutorial gacha.
• Tier snapshot — Marina is valued for Assist Neutral coverage, not tier rank.
• Pull strategy — do not roll specifically; dupes come naturally.

Marina plays as a Assist Neutral unit with the Passion (情熱) emblem. Assist-slot buffer or healer who self-charges and stabilizes the team's skill economy. In auto-battle defense, slot Marina on the Assist line of your 10-unit formation — their epithet "Travelling Merchant of Everything" reflects a Eldorana kit built for early-to-mid content.

• Formation slot — Assist row; one of 1–2 Assist slots.
• Element coverage — Neutral matches certain Calamity weaknesses; swap Marina when defense element charts demand it.
• Emblem loop — Passion self-charges on action; no battery required.
• Skill priority — level Marina'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 Marina inside Dot Abyss through the standard roster menus. Japanese players know the unit as マリナ — 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 Marina'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 Marina by understanding availability (Not in tutorial gacha) 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 Marina's build means leveling skills, securing gear with the right stat rolls, and hitting bond milestones for permanent stat points. Marina is a Neutral / Assist / Passion (情熱) unit — every upgrade choice should reinforce that role.

Optimize Marina for launch-week defense and idle clears. Marina punches above SR weight in Assist slots until SSR coverage arrives.

• Defense template — slot Marina on Assist; 1–2 Assist support.
• Emblem meta — Passion units run independently; great for flexible slots.
• Element swap — keep Marina 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.
