Pariah's Shield

Requires attunement.
You gain a +l to AC for every two allies within 5
feet of you (up to a max of +3) while you wield
this shield. This bonus is in addition to the
shield's normal bonus to AC.
When a creature you can see within 5 feet of you
takes damage, you can use your reaction to take
that damage, instead of the creature taking it.
When you do so, the damage type changes to
force.
