This shield is dark in color and seems to mute the noise of weapons that strike it. While attuned to this steel shield, you gain resistance to thunder damage, and you can use your reaction to extend that resistance to one creature adjacent to you until the start of your next turn whenever you or an adjacent creature takes thunder damage.

Additionally, the shield has 3 charges, and it regains 1d3 expended charges after completing a long rest. As your action, you can cast spend a charge to cast thunderwave as a 1st-level spell (save DC 14). Each additional charge spent increases the spell level and save DC by one.

If you are subjected to an effect that deals 30 or more points of thunder damage before your resistance, the shield regains one spent charge.

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.
