Caligarde's claw

Caligarde's claw was a conjuration spell that created an invisible claw made of pure force, similar to the various Bigby's hand spells.

Effects
This spell could be cast at a target up to 60 yd (55 m) away. The target could be a particular entity or a 20 ft (6.1 m) diameter circular area. If the target was an individual, that person had a chance to resist the spell, in which case the claw was created 10 ft (3 m) away in a random direction, as if it were a missed grenade-like missile attach. Once cast on an area, either intentionally or by missing the intended target, the claw attacked the nearest being within its 10 ft (3 m) reach. Caligarde's claw attacked once per minute for a duration equal to the caster's level, and with the same skill as the caster, but with the added feature that once it hit, it never missed again. If this spell successfully targeted an individual, then it was not fixed in place but continued to attack that being even if it moved more than 10 ft (3 m) away. A person taking damage from Caligarde's claw could not engage in normal spell casting, but items that did not require an intricate activation sequence could be used.

Only magical barriers, such as anti-magic shell, shield, Bigby's interposing hand, and the like, could block the claw attack; physical counterattacks had no effect. Caligarde's claw could be destroyed by dispel magic and similar effects.

Components
In addition to verbal and somatic components, this spell required a dried or preserved foot or claw as a material component.

History
This spell was published in "Volo's Guide to All Things Magical" and became generally known to the magical community.
