Here is a build guide for Rebecca in Duet Night Abyss, including the best weapons, Demon Wedges, team compositions, and more.

Rebecca is at the top of the meta for the best DPS units in Duet Night Abyss. This is due to her summoning mechanic, which offers a wide AoE damage. This makes her a good unit for clearing groups of enemies. To further take her efficiency to the next level, you need to consider the right weapons, combat partners, and Geniemons to pair with her.
With that said, this guide will cover the best build for Rebecca in Duet Night Abyss, including the team compositions that suit her.
Best Weapons for Rebecca in Duet Night Abyss

Melee Weapon
Siren’s Kiss is the best weapon for Rebecca for the enhanced skill range. On top of that, this weapon also increases attack speed with each normal attack. The attack speed boost can stack up to 12 times. With the right combo, you’ll be able to increase the uptime of this buff. However, keep in mind that the effect resets when switching weapons.
Alternatively, you can go for the Vernal Jade Halberd. This weapon increases attack speed and deals bonus damage to enemies afflicted with bonus effects. Based on your preferred gameplay, this weapon can be a viable option. However, the Siren’s Kiss is still a far better weapon.
Ranged Weapon
If you are looking for a ranged weapon for Rebecca in Duet Night Abyss, go for the Destructo. This Grenade Launcher increases skill range by a good amount. Additionally, projectiles from this weapon can knock enemies in the air. This adds a bit of crowd control to your build.
Silverwhite Edict is also a good alternative if you prefer a higher fire rate weapon. It boosts attack speed whenever this weapon is fired and triggers a bonus effect. This effect can stack up to 10 times. However, the effect expires when switching weapons. It has a similar mechanic to Siren’s Kiss, but with different effects.

Skill Priority for Rebecca

While leveling up Rebecca, consider prioritizing the following skills:
| Skill | Priority | Description | 
|---|---|---|
| High | Lada Lovedew (Ultimate – DMG Skill) | Deals Hydro Damage to nearby enemies; the damage is increased based on the number of Poison of Love stacks inflicted on the enemies. | 
| Mid | Aurelian Caress (Skill – Summon) | Summons 1 Aurelia Aurita. A maximum of 3 can exist at the same time. Aurelia Aurita: Inherits 100% of Rebecca’s stats, continuously dealing Hydro Damage to nearby enemies. | 
| Low | Truelove Trial (Passive) | When dealing damage with a melee weapon or [Aurelia Aurita]’s attack, inflict 1 stack of Poison of Love on the target, up to 6 stacks. Poison of Love: Deals Hydro Damage once every 2s. When defeated, enemies inflicted with Poison of Love transfer the debuff to nearby enemies based on the current stack count and remaining duration. | 
Best Geniemon
As a Hydro unit, the best Geniemon for Rebecca in Duet Night Abyss is Hydrelf. This is because it increases the entire team’s Hydro damage. This buff includes the main character and Hydro Demon Wedges with Griffin, Typhon, and Cevenanter Prefixes. You can get Hydrelf by unlocking the Bard’s Tome Battle Pass and reaching Level 30.
Alternatively, you can have Dripplet and Bunniva. You can get these Geniemons by capturing them in the wild. You will need to feed them treats for a chance to befriend them.
Best Rebecca Team in Duet Night Abyss
For the best team or combat partners for Rebecca, it’s Dephne and Phoxhunter. This lineup is a good mix of healing and damage potential.
Daphne has one of the best healing and damage buff kits in Duet Night Abyss. Additionally, she is also unlockable just by progressing through the game. That said, she will fit nicely with this team composition.
Phoxhunter is another character that provides shields and can increase weapon damage. The best part of this is that they are the main characters of the game. This means you get them for free at the start. You won’t have to grind just to unlock them. However, you still need to farm materials to level them up fast.
Alternatively, you can also have Truffle and Filbert join your party. The duo provides decent healing and damage boost buffs for the team.
