So I have a big bad lich that I want the PC's to encounter later in the game at a higher level. In order to fool the party into thinking he is dead he is setting up a simulacrum in his old hide out. Contingency effect in place so when the simulacrum is killed it pops an illusion of bones and cloth instead of ice along with fake phylactery.
However one of my players has deathwatch eyes. Which according to text.
"You instantly know whether each creature within the area is dead, fragile (alive and wounded, with 3 or fewer hit points left), fighting off death (alive with 4 or more hit points), healthy, undead, or neither alive nor dead (such as a construct)."
As for Simulacrum.
"Simulacrum creates an illusory duplicate of any creature. The duplicate creature is partially real and formed from ice or snow. It appears to be the same as the original, but it has only half of the real creature’s levels or HD. You must make a Disguise check when you cast the spell to determine how good the likeness is. A creature familiar with the original might detect the ruse with a successful Perception check (opposed by the caster’s Disguise check) or a DC 20 Sense Motive check."
Would he know this Simulacrum is neither alive nor dead? Or would the Simulacrum be shown as undead? Or would I need to make a Disguise check for him to see through?
