RQ/Greyhawk Sorcery Spells

The following spells are based on the most famous "Named Spells" of the World of Greyhawk, adapted for use with Sandy Petersen's Sorcery System. Unlike most sorcery spells, they take up more than 1 point of INT to memorize, as each spell is actually a matrix of several effects bound into one spell.

BIGBY'S BATTERING GAUNTLET
3 Points Memorization
Ranged, Active
 This spell creates an illusion of a large battering ram with a head shaped like a clenched fist. For every 2 Intensities in the spell, it does 1d4 points of structural damage. This spell has no effect when employed against naturally living entities, or if used against anything but a portal (door, porticulis, drawbridge, etc.). Only one such spell can affect a given portal at any one time.
 If used against a structure that contains a bound spirit, the caster must overcome the magic points of that spirit with his own in order to cause damage that round.
 

BIGBY'S CLECHED FIST
3 Points Memorization
Ranged, Active, Maintained
 This spell creates a large disembodied hand clenched into a fist. This fist is under the mental control of the caster, who may use it to strike opponents using his own Fist/Brawling and Martial Arts skill percentages, or his skill in this spell, whichever is lower. Each such blow does 1d6 damage and has an effective force for knockback equal to 3x the rolled damage.
 

BIGBY'S CONSTRUCTION CREW
2 Points Memorization
Ranged, Active, Maintained
 This spell creates illusionary hands that can perform any craft
the caster is skilled in. For every three Intensity in this spell, 1
pair of disembodied hands are created. All such hands come
equipped with appropriate tools, and will work together like a construction crew.
 All such hands use the caster's skill in the requisite craft, but each makes its own individual skill rolls (the caster of this spell does not gain skill checks in his craft while using this spell). Any pair of hands that fumbles its skill roll vanishes.
 The hands will only perform crafts, not fight or damage any living creature. The only other (non-Craft) skills they will perform are First Aid, Shiphandling, and Play Instruments. When used with Multispell, each set of hands must be set at a seperate task (i.e. one group of hands could saw and nail boards for the side of a barn, while another paints the wall).
 

BIGBY'S FANTASTIC FENCERS
2 Points Memorization
Ranged, Transient
 This spell creates an illusionary, disembodied hand equipped with a weapon (the Intensity of the spell dictates the type of weapon created). The hand will engage and fight an opponent designated by the caster, using 1/2 the caster's skill (any 1H melee weapon skill will suffice). If employing Multispell, the caster need not concentrate on any individual hand to keep the spell functioning, but he may not perform any other action while the hands fight, or his concentration will be broken and the spell ended.
 At 2 Intensity, the hand weilds a Dagger.
 At 4 Intensity, the hand weilds a Rapier.
 At 6 Intensity, the hand weilds a Broadsword.
 At 8 Intensity, the hand weilds a Longsword.
