Behemoth’s heart (Set)

Armor (shield), unique (requires attunement by a fighter)

This metallic, dark grey +2 shield is an enlarged and reinforced heart of an elder dragon that has been magically reduced in size. A loud heartbeat can be heard when it blocks incoming attacks.

Radiates: Abjuration, evocation, and transmutation.

Power: This shield grants advantage when making saving throws against forced movement or being knocked prone by magical or nonmagical means.

Power: You have advantage on saving throws against breath weapon attacks.

Power: You may use this shield as a martial weapon to deal 1d6 force damage and shove the creature hit 5 feet away from you (no save).

Power: You gain behemoth’s heart. As an action, you loose a deafening roar that forces all creatures within 10 feet to make a Constitution saving throw or become frightened of you for 1 minute. If a creature has resistance to thunder damage, they have advantage on this save. You may use this power once per short or long rest.

Set Bonus: If you are attuned to both the behemoth’s claw and behemoth’s heart, you gain immunity to thunder damage. In addition, you gain a fly speed of 60 feet and the ability to hover.
