I believe you actually don't gain or lose any abilities with the mask and that it only impacts social interactions.
Edit. Watched the video again and the racial ability changes so mayne healing does too. I dont understand an appearance changing abilities.
Yep. Sven said it changes talents and abilities. I guess since the mask is powered by source, you aren't changing just your appearance, but shapeshifting in a more profound sense. (Think D&D where druid's elemental shapeshift grants more magical abilities).
I am curious if it removes the undead talent (and thus healing damage) when you are in a different form. I seem to recall they had said that the mask doesn't work in combat, but that was a long time ago and may have changed.
