Telepathy (Compulsion) [mind-affecting]
As sleep, except as noted here.
A sleep spell causes a magical slumber to come upon 4 Hit Dice of creatures. Creatures with the fewest HD are affected first.
Among creatures with equal HD, those who are closest to the spell's point of origin are affected first. Hit Dice that are not sufficient to affect a creature are wasted.
Sleeping creatures are helpless. Slapping or wounding awakens an affected creature, but normal noise does not. Awakening a creature is a standard action (an application of the aid another action).
Sleep does not target unconscious creatures, constructs, or undead creatures.
For every additional power point you spend, this power can affect targets that have Hit Dice equal to 4 plus the additional points spent. If you instead spend 11 additional power points, you can completely remove the Hit Dice cap for the power's effect within the area.
