Cushions an area/object
- "Harry heard the cart smash into pieces against the passage wall, heard Hermione shriek something, and felt himself glide back toward the ground as though weightless, landing painlessly on the rocky passage floor."
The Cushioning Charm (Bolstra) creates an unseen softening effect on target surfaces. It is primarily used in broomstick manufacturing to make the brooms more comfortable for riders.
During their break-in of Gringotts Wizarding Bank, Hermione Granger used this charm to protect Harry Potter, Ronald Weasley, Griphook, herself, and an Imperiused Bogrod when the Mine Cart in which they were riding derailed after passing through the Thief's Downfall.
