I'd love if we had more transformation options, especially for Beastmoon or outside of it. Since there's so many beautiful models that could be reused.
I'd turn into Wraith or Lost Soul. Also another thing, they could just add the ones that are already available through quests, like the Shadow Weavers. It would make things have more variety. Instead of having reskins of the same ones x3
Siren like teles in atlantea for me or the lady of the lake
maybe an utility from the monstrology after collecting enough animus from a creature you can craft polymorph potion or even better switch to it when you want
I've thought about the exact same thing for Monstrology. It would give me a reason to do it if I could craft a potion like that. Would be awesome, also for Beastmoon if we had more forms.
