Seliel

Unique succubus. Seliel can be recruited after triggering 3 of her events. Her events can be found in portals with forest tile events, when you have a free party slot. On every event, she will offer you a creature: a bird, a wolf, or a mule. You can say yes or no to all animal offers, regardless she will still be eligible for recruitment on your 4th meeting.

Combat wise she is fast, you can almost disregard her as a succubus entirely. Seliel is useful as an early game scout, if you don't have anything else. She also comes with her own gear upon recruitment. She can tame animals, but it requires specialized training, capture more useful creatures.
