Donut's Atrocity-class spell that manifests a colossal ghostly cat paw the caster must swipe with personally.
Astral Paw was one of the two spells Princess Donut cast for her third Atrocity, the other being Binjabi. It manifested as an enormous glowing outline of a cat's paw hovering over the hole of Larracos just outside the Nest Tower, growing large enough to catch thousands of floating soldiers and the god Meatus at once. The trapped elves, Gnolls, and cyborg Reavers woke from their frozen state and bunched screaming against its underside while Fleshers dissolved them.
The spell's cruelty is that it will not act on its own. The paw simply hovered, waiting for Donut. She told Carl she should not have picked it because she had to do the killing herself. With Li Na weaving a lattice of chains below, Donut stretched her real paw over empty air and swiped downward in sets of three baps, each mirrored by the giant paw slamming the captives through the chains. She repeated it dozens of times until the screaming stopped, an act the system logged as a War Crime.
A massive glowing ethereal outline of a cat's paw, claws extended, hanging in open air above the city.
The finisher spell that annihilates the enemy army above Shanty Town, at the cost of forcing Donut to do it by hand.
