Rhea

Rhea, also known simply as 'The Fox Succubus in the Succubuspedia, is the first optional encounter in the Underground Grove. Similarly to the Cow Succubus, she belongs in the Beast Clan. She can be described as "odd", for she seemingly waits in the ruins for her long-lost love to return to her. It's unclear who exactly she is referring to, but one can only speculate it is one of her previously drained victims, perhaps a strong warrior that almost defeated her.

Strategy
This is a pretty tough battle, so Iron Will pre-fight is strongly recommended. Opposite to the Cow Succubus, Rhea is weak to physical attacks, but one can also combine them with the use of Blue Thunder to try and stun her. This is especially useful against her highly damaging attacks. For further advice, refer to the combat guide.
