New ACKS Spells 2 - Utility

Today I've got an upgrade of an old standby, as well as two (slightly silly) mount-related utility spells:

Deep Slumber (Ench)
Arcane 3
Range 120'
Duration: 4d4 turns
A more powerful version of the common Sleep spell, Deep Slumber causes up to 24 HD worth of living creatures within range to save or fall asleep for the duration (the save may be vs Death or Spells, as the judge's discretion).  There is no HD cap per creature, and the caster may select the order in which he desires to effect targets, subtracting them from his HD budget.  Affected creatures may be awakened as per the Sleep spell.
(Maths: Enchantment, target asleep (15), 24 HD of creatures (x3), only living targets (x0.75), range 120' (x1.1), duration 4d4 turns (x1.2), save avoids (x0.5) = 29.7)

Estenmar's Equine Enhancer
Arcane 2
Range: Touch
Duration: 8 hours
This spell doubles the movement rate of one willing creature touched for eight hours.  Typically used by the originator on his horse for long overland journeys, the spell is equally effective on one's travelling companions or oneself while fleeing a dungeon in a pinch.  Whether unintelligent animals are 'willing' is an open question; they might be willing recipients of benign magics, or they may need special training.  Ask your DM if Estenmar's Equine Enhancer is right for you.
(Maths: Movement, double speed (5), one willing creature with normal carrying capacity (x0.8), range touch (x1), duration 8 hours (x4), beneficial effect (x1) = 16)

Pegastasize (Transmog)
Arcane 4
Range: Touch
Duration: Permanent until dispelled
Pegastasize is a specialized spell developed by a wizard who was trying to turn horses into pegasi with Polymorph Other, but who then had to deal with the complete training wipe that ensued from inheriting their mental characteristics.  Pegastasize avoids this problem, transforming a horse into a pegasus without altering its mental characteristics.  If used on a pegasus, pegastize causes its wings to retract, yielding a normal horse.  In both cases, the subject receives a saving throw vs spells, and if the target is unwilling, the caster may have to roll to hit in order to successfully touch them with the spell.
(Maths: Transmog, Total transform of living creature with physical characteristics and attacks (55), limited type to transform to (x0.75), limited type of subject (x0.75), HD limited to caster level and 2x target level (x0.75), range touch (x0.6), attack throw required vs unwilling target (x0.75), indefinite duration (x3.5) = 36.54)
