Siren's Kiss increases Rebecca's Skill Range and gives her ATK SPD, which all move to her Aurelia Aurita summons. They inherit 100% of Rebecca's stats, which means the jellyfish will have a bigger AoE when she summons them.

Wanewraith grants Rebecca 24% Skill DMG, which is a decent buff for her summons.

Vernal Jade Halberd increases Rebecca's ATK SPD by 25%, in addition to an extra 45% DMG on enemies afflicted with bonus DMG. Bonus Effect can easily be applied by dealing damage with a weapon or certain skills, so as long as the enemy has the Bonus Effect debuff, the Polearm will grant the DMG Bonus.

Destructo grants Rebecca 36% extra Skill Range, which is amazing for her mechanics.

It's always important to go for stats weapons when building Rebecca in DNA, as they boost the utility and DMG of her summons. Silverwhite Edict is the same, where the Ranged weapon will keep stacking ATK SPD buffs, as long as Rebecca is triggering Bonus effects through the gun.

Bahamut's Misty veil gives Rebecca a whopping 30% extra Skill DMG for her summons. Not only that, but it also keeps increasing her ATK SPD and summons' Range.

Another Demon Wedge that notably increases Rebecca's Skill DMG. It also grants her the ability to slightly buff her team's ATK, which is a good thing for an off-field Rebecca.

Typhon Prime Serenity massively increases Rebecca's stats, especially her ATK%. It also grants her the ability to regenerate her team's Sanity every three seconds. It's another off-field utility for Rebecca when she's operating as a Combat Partner.

Typhon Prime Uplift gives the same stats as the previous one, with another passive effect for Rebecca. When building Rebecca with the Typhon Prime Uplift Demon Wedge, she'll buff her team's DMG by 11%.

A perfect Demon Wedge to build Rebecca with in Duet Night Abyss. It gives her an extra Hydro ATK%, Skill DMG%, and Skill Range%. Most of what she needs is in one Demon Wedge.

Luckily, there's another Griffin's Seawave Demon Wedge right next to the Wildfire one, which is the Midnight Sun. It grants Rebecca the same first two stats as Wildfire, which are Hydro ATK% and Skill DMG%. However, instead of Skill Range, it grants her Skill Duration. It's a good stat to allow her summons to stay longer on the field.

Hydrelf helps Rebecca operate as an off-field Combat Agent by increasing her and her team's DMG as long as she's summoning her Aurelia Aurita. It also increases Rebecca's ATK% alongside her team if she is the main DPS of the team. It's a good passive to have on Rebecca if you're playing her in Co-op Commissions.

Bunniva increases Rebecca and her team's ATK% when she summons it. It also buffs her and her team's Hydro ATK% if Rebecca was operating as the main DPS.

Build Rebecca with Dripplet as the last option, if you haven't found Hydrelf and Bunniva yet. Dripplet slightly increases the team's ATK% with an even smaller effect from its passive.
