Bigby's grasping hand

Bigby's grasping hand was an evocation spell that created a hand of force to grapple with an opponent. Clerics who cast this spell named it for their deity&mdash;Lathander's grasping hand, for example.

Effects
This spell was one of the Bigby's hand family of spells. It created a hand about the size of an ogre or about 10 ft (3 m) tall with a splayed finger span of about the same distance (earlier versions could be even larger   ) that could be used to grab and hold a creature. All versions of this spell relied on the caster's senses to detect and locate a target, the fist did not have senses of its own. But once a target was designated, the hand would unerringly stick with the target regardless of invisibility, polymorphing, darkness, or other means of concealment or disguise.

The earliest versions never missed the target once it was designated,  but later versions performed repeated melee attacks until the grapple succeeded or until the spell expired. A successful grab immobilized the target. The grasping hand could also be used in the same manner as Bigby's interposing hand or as an improved Bigby's forceful hand with greater strength. For the earlier versions, the weight of the target determined the reduction in movement rate. A 1,000 lb (455 kg) creature could be held motionless, while a 16,000 lb (7,270 kg) creature would be slowed to half its normal movement speed.

Range and duration varied widely over the history of this spell. For the earliest versions, a wizard that had advanced just enough to cast this spell could control the hand for 14 minutes and extend its reach to 140 ft (43 m) indoors/140 yd (128 m) outdoors. Later versions lasted only a minute or two, but the reach was extended from 120 ft (36.6 m) to 230 ft (70.1 m) at a minimum.

For all versions of this spell, the health of the hand was the same as the caster's uninjured health.

Components
In addition to the verbal component, all versions required somatic gestures. After the Sundering, the hand imitated the movement of the caster's hand for the duration of the spell. The early versions required a glove made of leather,   but after the Sundering, the material components were refined to an eggshell and a glove made of snakeskin.
