Truffle and Filbert occupy a reliable Anemo support slot in Duet Night Abyss. Their healing and team damage buff scale off Max HP, and their strongest moments happen while mounted, charging through enemies and leaving sustained utility in their wake. Build them to stay on the field longer, spend Sanity efficiently, and keep buffs up for your DPS.
Core build priorities (what actually moves the needle)
- Max HP first: both healing and a portion of damage scale with HP, making it the most impactful stat.
- Skill uptime: stack Skill Duration and Skill Efficiency to extend heals and buffs and to get more value per Sanity spent.
- Max Sanity: more Sanity means more time riding/charging and more casts before you need to disengage.
In short: HP for throughput, Skill Duration/Efficiency for consistency, and Max Sanity for staying power.
Recommended weapons (melee and ranged)
| Slot | Weapon | Why it fits |
|---|---|---|
| Melee | Undying Oneiros | Massive Max HP increase and stacking HP on bonus procs; best-in-slot for raw HP scaling. |
| Melee (alt.) | Punitive Inferno | High Max HP plus conditional Skill Duration; a workable alternative if Oneiros isn’t available. |
| Ranged | Arclight Apocalypses | Skill Duration boost and team-friendly effects; supports longer healing/buff windows. |
Demon Wedge loadout (slots, core, and tolerance)
| Slot | Wedge |
|---|---|
| 1 | Nirvana |
| 2 | Prime • Morale |
| 3 | Squall • Midnight Sun |
| 4 | Whispering Zephyr |
| 5 | Wings • Inspo |
| 6 | Gleaming Whipsword |
| 7 | Wings • Eternity |
| 8 | Intrepidity |
| Core | Helido |
This configuration prioritizes HP scaling, sustained skill uptime, and supportive utility. With the setup above, total Tolerance sits at 105.5/100; Helido at +5 raises max Tolerance to 117, making the spread viable. Expect to spend 4 Track‑Shift Modules for the slot adjustments required.
Skill kit and recommended upgrade order
| Category | Skill | What it does |
|---|---|---|
| DMG/Heal | Trotters Trot‑Trot | Filbert charges, dealing Anemo damage in a line and an AoE on impact; heals allies and buffs their damage while active. Replaced by Charge‑Charge when mounted. |
| DMG/Heal | Trotters Charge‑Charge | Hold to sustain a charge that consumes Sanity, dealing Anemo damage along the path and an AoE on stop. |
| Buff/Movement | Tummy Full, Hands Full | Mounts Filbert, grants Passion For Work and movement speed, and deals contact Anemo damage while moving; remounting dismounts and triggers Trot‑Trot once. |
| Passive | Chop‑Chop, Commissaries! | Gains Heavyweight stacks while moving; increases damage dealt and reduces damage taken. |
| Passive | Combat Supply | Chance to drop an Ammo Supply Chest when dealing skill damage. |
Upgrade priority: DMG skills first for throughput and healing windows, then Passives for Heavyweight ramp and supply drops, then Buff for the mount utility. This aligns both with HP scaling and the mounted play pattern.
Introns that meaningfully affect the build
| Intron | Impact |
|---|---|
| I1 | Slows the decay of Passion For Work, helping you stay mounted longer. |
| I2 | Grants an Attack boost to teammates based on Truffle’s Max HP when using a skill (short duration, capped effect). |
| I4 | Raises Heavyweight stack cap and grants stacks on mount start, accelerating early uptime. |
| I6 | Picking up certain field items adds stacks that raise Skill Damage for a short time, stacking up to three times. |
These introns convert your HP investment into team damage and make the mounted loop more forgiving and potent.
How to play Truffle and Filbert (short loop)
- Open with Tummy Full, Hands Full to mount and start moving through enemies; you’ll deal contact Anemo damage while building Heavyweight stacks.
- When you need burst area coverage or a dismount, trigger Trotters Trot‑Trot; when already mounted, hold to use Trotters Charge‑Charge for sustained line clears and continuous healing at the cost of Sanity.
- Keep an eye on Sanity. If you need to conserve it, switch Truffle to a partner slot and let a DPS rotate in while her buffs and healing windows do their work.
Teams that benefit from Truffle and Filbert
- As a combat partner for DPS carries like Rebecca, Psyche, or Lynn, Truffle keeps the main damage dealer safe and buffed.
- Elemental squads that can field at least two of the same element benefit from the Resolve buff she can provide as a partner, particularly for low-HP DPS playstyles.
- Electro-focused teams also profit from her steady healing and damage boosts while they set up sustained damage.
The common thread: bring a consistent on-field DPS and let Truffle’s HP-based kit handle sustain and enabling.
How to unlock Truffle and Filbert
- Free path: complete the Tutorial: Covert Commissions special side quests and the Go, Geniemons! quest line.
- Secret Letter path: spend 10 Secret Letter Clues for Truffle and Filbert’s letter, clear a Covert Commission stage to open it, and collect Thoughts. You’ll need 30 Thoughts to unlock the character. Letters are not guaranteed to drop a Thought.
Optional picks that round out the support role
- Geniemon: Shroomie complements the kit with healing and can boost Anemo attack and Max HP for the squad.
If you lack specific wedges or weapons, stay anchored to the build’s fundamentals: prioritize HP on gear, then stack Skill Duration/Efficiency and Max Sanity. The kit rewards time on the field and smooth Sanity management more than any single niche roll.
