Drain
From UnderlightWiki
With Drain, you are doing something totally different with the essence than with the other art. Instead of casting the nightmare away, wherever you send it to when banishing or imprisoning, you are absorbing it into your own avatar And a transformation occurs, transforming it into Dreamsoul or another focus art. The effect of this act upon the avatar of the one evoking it is an ongoing debate within the dream.
