This is a medium sized figure-of-eight style Mithral* shield with the head of a charging ram emblazoned as the shield boss.  While holding it, you have a +1 magic bonus to AC. This bonus is in addition to the shield's normal bonus to AC.

When attuned, the shield conveys several abilities:

• Allows you to take a bonus action and use the shield to absorb the physical damage from a melee or ranged attack. You can absorb 1/2 the physical damage done to you and turn them into charges.  The damage absorbed  does not affect you (the attack does 15 pts of damage, You gain 7 charges and take 8 damage).  The Aegis of Hekter can store a maximum of 15 charges.  If the charges are at full then no more damage can be absorbed.   As the number of charges created increases, you begin to breathe steam out of your nose and your eyes turn red. All stored charges are lost within a few minutes after combat ends.
• If the shield has any charges stored, you can use an action to spend any number of those charges to make a melee shield bash attack and to shove a creature.  You must move at least 10 feet in a straight line immediately before making the attack. When you make the shield bash melee attack, you add the charges spent to the shield-bash's damage roll and  the target must also make a strength saving roll vs 9+your strength bonus plus the number of charges spent.  If he succeeds, he holds his ground.  If he fails, you push the target up to the number of charges spent in feet away from you.  Creatures one-two size larger than you get advantage on the saving throw, while those 3 sizes larger or more are immune to the push.

 

*Mithral is a light, flexible metal. If the armor normally imposes disadvantage on Dexterity (Stealth) checks or has a Strength requirement, the mithral version of the armor doesn't.

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.
