Black Ankh of Set

Wondrous item, very rare (requires attunement by a follower of Set)

A black ankh of Set appears as a cobra in the shape of an upside-down ankh. Such an item is given only to the most devout and wicked followers of Set. This item exudes an unholy aura that grants you a +3 bonus to AC and resistance to poison damage while you wear it. A bearer of a blank ankh of Set is not prevented from teleporting outside the Pyramid of Set from within.
