Dridaridos evolution method ideas

[Willow Hallowes]

Hey so i am working on updating a lot of things on my project i’m still in the midst of planning out (its always good to plan stuff out and work on things during the process of planning before getting into game making) and I was wondering what I could do for my Drider inspired evolution for Ariados. I know i want it to be a female only evolution but i’m unsure on what else i should include in the evolution conditions of it. Any ideas?
