Review

We have reworked our tier list owing to multiple meta shifts and how we rate characters. As such some of the reviews (especially of older characters) might not match the tier list ratings. Please prioritize the ratings given over provided Review. We will be working on updating all reviews, but it is a time-consuming endeavor.

Last Updated - August 11, 2025

Given out for free after Story Chapter 5, Rebecca’s role has always been this Fringe Buffer/ DoT amp/ Mana Burn support unit that sees her outclassed in a variety of areas. Several balance patches have given her the reputation as the fastest Mana Burn in the west, but nothing to catapult her into meta status. Enter the July 2025 Balance patch, which gave Rebecca stronger steroids for herself and her ally, Dispel (because it’s in vogue right now) and a streamlined attack pattern.

Rebecca’s steroid <Synthetic Adrenaline> now goes after the unit with the highest ATK, giving herself and her ally Critical DMG on top of the ATK and Speed, as well as a small Mana Battery. This essentially turns her into a 2nd Eve, another top tier buffer, with her own pluses. Her fast AOE Mana Burn, Heal Reduction, and Dispel on demand gives her excellent tempo control. Moreover, her DoT amp also allows her to be easily slotted into the ever growing Burn team, essentially adding fuel to the fire. Rebecca is an extremely flexible buffer role and can easily see slot ins across content, for both New and Old Players.

Pros

  • Insanely fast Mana Burn/ Healing Reduction/ Dispel on demand.
