The warlock can use its daily on undead (the charmy illusiony thing). So yes, Eyebite is legit.Sashi said:The question is: should the skeleton be immune to eyebite because of fluff reasons (i.e. "the skeleton has no eyes") or for balance reasons? Because the fluff is irrelevant to game mechanics.
Unless the statblock says "It's immune", then it's not unless you rule 0.
Also, not only does the rules say "The skeleton knows what you did to it" re Divine CHallenge, but that Int 3, if I recall, is high enough to be able to speak.
The mark, in general, is to prevent big nasty monsters from charging past you and attacking the wizard. The AoO prevention isn't a bad trick tho.
