Attuning to it requires pricking your finger and allowing a drop of blood to be absorbed into the wood, giving it a breath of new life. Once attuned, if anyone other than you attempts to attune to the pendant, it immediately collapses into dust and is destroyed.

you land a critical hit on 18,19 and 20

additionally after you attack, you can cast once per turn a 3rd level smite as a free action

While using the pendant to concentrate on a spell, you may make a separate concentration check for the spell that the pendant is maintaining, but you do not have to. You can decide to use separate concentration checks after rolling the first check.
