Locking Armor (5e Equipment)

Armor (plate), rare

This armor resembles a completely innocuous suit of plate mail.

However, whenever the wearer performs an action, there is a 5% chance (roll this in secret) that the joints in the armor suddenly lock up for 1 minute. The creature wearing the armor is restrained for the duration, and is unable to perform attacks or cast spells with somatic components.

Casting remove curse or dispel magic on the armor while it is locked unlocks the joints and allows the creature wearing the armor to move freely again.
