Leucocoryne has the same ability Edelweiss has, and I'm almost certain I've seen it on another girl as well.
Not sure if Toad Lily's ability is available elsewhere. At least, I haven't seen it (yet).
2 girls have [Stage] -50% Dam from small pests when moving ability.
- Japanese Iris and Toad Lily
3 girls currently have the ability "+10% HP for all Squad members after moving through a Pest Nest Node"
Edelweiss evolved Dianthus and evolved Leucocoryne
