Bartholomew's backup belt barrier(physical)

Created to protect explosive miners, shock troops, and eccentric engineers. This bulky beige belt attachment is as clunky as it is useful. Often used by those in highly volatile environments.  Wealthy patrons might equip their security teams with these belts during high risk trade negotiations. 

While equipped, the user has a 5ft penalty to movement speed if they don't have Heavy Armor Proficiency. 

You can use an action to activate the barrier, consuming 1 charge. While active, the wearer receives 15 temporary hit points lasting 1 minute. This damage only protects the wearer from non-magical non-elemental damage. The barrier requires 5 minutes after activation to be activated again. 

When created, the Bartholomew's backup belt barrier contains 5 charges, when all are used up, it becomes useless.
