OK.
From the test's start, I've seen the following:
[spoiler]
1. the Lifestealer illusion's elemental is an egg. not sure if this is a bug or not, but it's rather useless.
2. I can't make rituals with summoned creatures. I go through the motions, click the create ritual button, but no ritual is created.
3. spells don't always work under the illusions. this includes my spells and the illusion's spells. It seems the the Book of Healing spells don't work, and the Wodin's Guard spell does.[/spoiler]

A small update on the spells issue:
It seems that spells cast on someone under an illusion are problematic.
The player's original name doesn't work as a target for the spell, and spells cast on the illusion name seem to work.

[spoiler]Soldier of Loreroot name and title overrides Tainted Warrior name and title, but Tainted avatar overrides Loreroot. there should probably be a check to prevent taking both at once[/spoiler]

Rituals were Working last I checked. Mur fixed those Reasonably Quickly.

elemental is not a lifestealer it is egg form

elite loreroot archers are scouts

illusion avys seem to stick when you dont have a default avy

some spells are not working
