[FGO] "The Bronze Castoria ?"
Arts up, atk up, np gain up and an aoe battery, she is almost like a tiny castoria in terms of looping support lol.
She is a decent sidegrade, you can do 50NP start CEs and single castoria + anning or swap her in after double castoria if your DPS has bad refund. Double Mary anning is a bit too meme tho.
