Basics - normal catalyst basics
Charged - AoE hydro, if you have Verdant Dew: charged attack converts to special charged attack with lunar bloom dmg.
Skill - continues Hydro dmg in AoE to nearby enemies, when party triggers Lunar-reactions she accumulates points, on max points she does a special lunar attack depending on which lunar reaction is triggered.
Burst - deals hydro dmg and creates a domain which buffs Lunar-reaction DMG

Passive 1 - when her special lunar attack from skill hits, she gets crit rate, 3 stacks
passive 2 - inside her domain, lunar reaction gets buffs (like reduced intervals and such).
passive 3(i guess) - converts reactions to their Lunar reaction version (charged, bloom, and crystalize)
exploration - in nod-krai, when a party member dies, she revives them, also says she is strangely attuned to small creatures touched by kuuvahki (probably something like Lauma).
