    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. Awakening a creature is a standard action,
    using your special character item to wake them.

    Sleep does not target unconscious creatures, constructs, or undead creatures.

    Material Component: A pinch of fine sand, rose petals, or a live cricket.

    Uses an altered Bioware version to get the lowest HD. It also takes into
    account range.
