[Pine]
Later, before they separated, Pine would turn to Naralis.
"Will healing spells work as intended on Ularan?"
[DM - Naralis]
"If Ularan requires healing then we are wading into darker tides that I expect fellow acolyte of Death."
Naralis looks pensive and thoughtful for a moment as he continues. "Ularan has lived long and has learned magic that did not exist before he did so. It's impossible to do so and remain completely as you were.
So yes, your question has merit. Many of the mundane spells that aim to knit flesh together would not affect his material form.
However he does heal naturally in time so a mundane non magical healer could aid him or even powerful magic that would speed this up" [Regenarate]
Naralis smiles at you but you notice that worry lines have appeared around his eyes. Your talk of Ularan being injured has distressed him even while he denies it's possibility.
"But worry not, all the aid he will need is simply allowing him to act.... Without the dark soul he wrestles with being given the same boon."
[Pine]
Pine frowns in thought, his own worry evident, although not for the same reasons, or not exactly. "I do not know a spell like that," he would say, glancing away from Naralis and towards where the tower loomed in the bleak landscape. "I do not have any strong healing spells prepared, only smaller ones given strength. Arya is better at healing the living than I, and so I prioritised other things. But now she cannot heal at all, if she is to be trapped in another form. Everything about this trip is worrying. I don't like it."
There was nothing either of them could do about that, however. Both of them were beset by circumstances not of their choosing or wishes.
"I truly do not know how I will be able to aid him."
