Exfoliation

While Karl answered mundane questions about his mental state for the doctors, Rae was hard at work with her advancement.

She had finished her exfoliation routine, and she had the perfect blend of blood in the bath for her upcoming advancement. She wasn't entirely certain what sort of skills it would give her when she did become a proper queen, but she had high hopes for this blend with the little bit of Totem Rank blood that she had managed to acquire.

It was only a few drops, but it contained ridiculously potent healing abilities, and it was two full Ranks over her.

She settled into the pool and began the work of pulling all the energy out of the blood. 

The process was simple for a Bloodbath Spider, and instinctive. You just absorbed all the energy from the bath, and then you found out if your body adapted to it well enough to break through the bottleneck and if you learned any new skills.
