From my in-game checks, a reanimate character doesn't count as "true" if IsUndead condition is checked on him.

So, I was wondering...what makes "Undead" an undead for the game? Is ActorTypeUndead?

Thanks,

If the creature has the keyword ActorTypeUndead, then they are as such.

Reanimated characters are different, if the actor from my understand has the keyword MagicNoReanimate, then this means they cannot be reanimated.

Yes. I know. It's because undead or elemental creatures cannot be reanimated, but you confirm me...reanimated aren't undead!! Sigh!!
