Anachronistic Shield

• A rectangular metal shield that is the board from the game, Anachrony.
• Once per long rest you can make a melee attack with the shield. On a hit the target must succeed on a 12 Wisdom saving throw or be affected by the slow condition, as detailed below, until the end of their next turn. 
• An affected target’s speed is halved, it takes a −2 penalty to AC and Dexterity saving throws, and it can’t use reactions. On its turn, it can use either an action or a bonus action, not both. Regardless of the creature’s abilities or magic items, it can’t make more than one melee or ranged attack during its turn.

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.
