Arrowsbane

A tower shield gifted by Durak, Master Blacksmith of Citadel Adbar, to his son, Huldohr Bristleforged. 

While you are holding a tower shield:

• You have half cover.
• You can spend an amount of movement equal to half your speed to have 3/4 cover until the start of your next turn. If you do this, then when you are an obstacle to a target (PHB, p. 196) you grant 3/4 cover instead of half cover.
• You can spend your action during combat to position your tower shield between an ally and an enemy, granting them half cover. No attacks can be made by you the round you do this.
• You gain a +2 to your AC versus Ranged attacks and Thrown weapons, as the projectile veers towards your shield instead. In addition, any projectile that passes within an aura of 10 feet of the shield are attracted to the shield, causing the attack to be aimed at you instead. You may deactivate the Arrowsbane ability by speaking a Dwarven command word.

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.
