Backpack Parachute

Whoever wears this backpack can deploy the
parachute as a reaction while falling, or as
an action otherwise. The parachute requires
a 10-foot cube of unoccupied space to deploy,
and it doesn't open fast enough to slow a fall
of less than 60 feet. If it has sufficient time
and space to deploy properly, the parachute allows its wearer to land without taking falling damage. Takes 10 minutes to repack.
