Armor (shield), rare (requires attunement by a Cleric or a Paladin or an Eldricht Knight)
This Shield is heavy and big, it grants +3 to your AC instead of 2.
When an enemy that you can see is about to attack with a weapon an ally of your, you can use your reaction to activate the shield.
Throw a D100, if the result is Less or equal 30 the shield will magically protect the target granting him +3 to his AC (this bonus is multiplicative with others effect that may be active).
This effect can be used only 3 times before a Long rest.
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.
Notes: Bonus: Armor Class, Cleric or a Paladin or an Eldricht Knight
