Creeping Tendrils are a high-demand resource in Duet Night Abyss, and you can burn hours for only a handful if you chase the wrong activities. Here’s how to target the right mission types, tune your team, and plan runs so you can stockpile hundreds without stalling your broader progression.

Creeping Tendrils in Duet Night Abyss (item vs. skill name)

There are two uses of the term “Creeping Tendrils” in the game:

  • The material you farm for upgrades and crafting.
  • Tabethe’s crowd-control skill, which summons tentacles that lift and immobilize enemies while adding Hydro support to the team.

This guide focuses on the material. Don’t confuse drops for the skill’s visual effect—one is a loot resource, the other is a combat ability.

Fastest method: run the Combat dungeon with the “Excavation” objective

Right now, the most time-efficient way to accumulate Creeping Tendrils is the Combat dungeon variant that rolls the “Excavation” objective. These instances consistently produce better Tendril returns per minute than general roaming or mixed-activity grinds.

  • Queue the Combat dungeon and prioritize the Excavation objective when it appears.
  • Rerun the same objective back-to-back while your buffs and rhythm are active.
  • Use your available drop-boosters to stretch each run; players report that generic commissions top out at roughly the high teens per clear even with a 100% booster, so the Excavation track is where efficiency actually scales.

If Excavation isn’t up, pivot to short, enemy-dense objectives until it rotates in. Don’t sink long sessions into lower-yield variants—rotation-based targeting wins out over time.

Secondary option: quick Covert Commissions clears (when Excavation isn’t available)

Covert Commissions are repeatable, level-40 missions with shifting objectives. They’re primarily designed for character, weapon, and Demon Wedge unlocks via Secret Letters, but you will incidentally gather materials while clearing them. For Tendrils specifically, set expectations: small bundles per run add up slowly.

  • Pick the shortest objectives to compress your clear times; hourly rotation lets you cherry-pick better layouts later.
  • Favor enemy-wave objectives when possible, as they pair well with AFK and semi-AFK setups.
  • If you’re optimizing your account anyway, you’ll still progress Letters and blueprints while scraping extra Tendrils between Excavation windows.
Note: Commissions are locked to level 40 content. If you aren’t there yet, focus your story progression and builds first to reach comfortable clears.

The fastest Tendril farms come from teams that control space and delete waves without constant input. Lean on these picks and priorities:

  • Rebecca AFK core: Deploy skills on cooldown and let the kit clear waves while you reposition or route to the next objective. This shines on Extermination-style maps and any dense-spawn objective.
  • Tabethe support: Provides crowd control via Creeping Tendrils and contributes passive Hydro damage to allies, stabilizing AFK and semi-AFK clears and keeping mobs grouped.
  • Stat focus: Skill Damage and Duration on wave-clear units; Skill Efficiency for supports that enable constant uptime; ATK only after your skill-focused stats are online.

If you’re short on specific units, prioritize one proven wave-clear DPS and two supports that extend skill uptime or lock enemies in place. The exact names matter less than maintaining continuous area control.

What to expect per run and how to plan your grind

Material drops fluctuate with objective type, run speed, and whether you activate drop boosters. Community results suggest that standard Commissions may yield only the teens per clear, even with a 100% booster, which is not sufficient if you need several hundred. That’s why Excavation within the Combat dungeon is the primary route—its enemy density and objective loop produce more useful stacks in the same playtime.

  • Target a fixed session length (e.g., 30–45 minutes) and measure your output. If you’re not netting meaningful gains, rotate objectives or adjust your comp.
  • Rerun strong rolls rather than chasing variety. Familiarity shaves seconds off each clear and multiplies over dozens of runs.
  • Bank boosters for Excavation windows; using them on slow objectives wastes their value.

At-a-glance: where to farm Creeping Tendrils

Activity Why it works Notes
Combat dungeon — Excavation High enemy density and efficient objective loop Best per-minute output; stack boosters here
Covert Commissions — short objectives Incidental Tendrils while farming Letters/blueprints Expect small bundles per run; rotate for faster maps
Extermination-style maps with AFK comps Hands-off wave clear maintains steady income Rebecca core; add Tabethe for CC and Hydro support

When to pause and pivot

If you’re still below the level-40 threshold for Commissions or you find your runs stretching past a few minutes each, you’ll gain more by strengthening one wave-clear unit and a support duo before returning to material farming. Once you can enter a map, deploy skills, and keep moving, Creeping Tendrils start to pile up without dragging the rest of your account behind.

Keep an eye on objective rotations and stick to the Excavation lane whenever it pops. With a fast-clearing comp and boosters saved for the right runs, harvesting the hundreds of Creeping Tendrils you need becomes a predictable, short-session loop rather than a grind that eats your week.
