    Enchantment (Charm) [Mind-Affecting]
    Level: Brd 6, Sor/Wiz 8
    Components: V
    Casting Time: 1 standard action
    Range: Close (8M)
    Targets: One or more hostile enemy creatures within a 5M-radius sphere
    Duration: One day/level
    Saving Throw: Will negates
    Spell Resistance: Yes

    This spell functions like charm monster, except that mass charm monster
    affects a number of creatures whose combined HD do not exceed twice your
    level, or at least one creature regardless of HD. Creatures with the lowest
    HD are targeted first.

    The charming makes each creature effected regard you as its trusted friend
    and ally. If the any target is currently being threatened or attacked by you
    or your allies, however, it receives a +5 bonus on its saving throw.

    Any act by you or your apparent allies that threatens the charmed creature
    breaks the spell. You cannot control a charmed creature directly, but it may
    help in battle and not attack you.
