Healing Rosina

Has anyone figured out how to heal Rosina’s animescence? I really want her as my healer.

This worked for me:

If you have enough Visage:expertise in parts, and have gone sharp in the tongue, then you can hold a exceptionally boring lecture about Visage, which does wonders for her health. I only had to repeat this twice to heal her.

There are multiple ways to heal her. In addition to the above, I know of the Drownie Hymn and Drownie Song of Counterpoint from Dahut. Being sharp in the tongue and lungs will make them more effective.
