Lauma
LaumaMain DPS

Nilou

Nilou is the core of this team, transforming standard Bloom cores into explosive Bountiful Cores with her passive. Her high HP pool also provides a minor Hydro application that fuels the reaction cycle.

Nahida

Nahida provides the essential, consistent Dendro application required to produce a high volume of Bloom cores. Her EM buff is also vital for maximizing the damage of the cores triggered by the Hydro units.

Sangonomiya Kokomi

Kokomi provides necessary healing to offset the self-damage from Bountiful Cores while contributing off-field Hydro application. Her presence ensures the team can survive the rapid explosions inherent to Nilou's Bloom teams.
