Top Characters for Prototype Amber
Barbara
A natural fit. Her entire healing kit scales with HP, and her Elemental Burst ensures this Catalyst’s passive is always activated. Prototype Amber solves her energy problems and enhances her whole kit.
Sangonomiya Kokomi
Kokomi’s healing and damage both scale off HP, and stacking with Prototype Amber complements her strengths. It also allows for fluid Elemental Burst uptime in Hydro-based reaction teams.
Lisa (Support Build)
Rare but viable. When used for utility, Lisa’s Burst uptime can benefit from energy regeneration, though she won’t maximize the HP value.
Mona (Emergency Healer)
If built slightly toward hybrid healing, Mona can leverage the energy regen and team healing during her Illusory Torrent and Burst animations.
