Azure's Shield is used by keeping track of every attack used against it. For example on an attack that doesn't land with an AC of 15. the opponent rolls a 13 for attack. record the 13 down as well as any other failed attack.(this will be recorded as Kinetic energy stored). When you choose to activate the shield and bash it against an enemy, opponent, or object. if you stored 268 of attack fails on your shield then said object/opponent is thrown that many feet. you can store up to 500 kinetic energy points in this shield at one time. When the shield is activated all the energy is released.
Shields require the Utilize action to Don or Doff. You gain the Armor Class benefit of a Shield only if you have training with it.
