is it worth to spend for her?

Of course, man. Just look at her thicc thigh

thicc indeed

Her thigh reminded me of some juicy ham. Nom nom

I would get her for elemental chains. Her Dream Within a Dream is a 3-hit water elemental skill. Missions requiring elemental chains will be easier.

She’s a limited time character so getting shards to max her LB will be difficult. Her Trust Master item is good.

Trust Master item is called Sacred Tree Hair Ornament.
