gives you a ac of +4 and has 1 charge. 

as a action you can use the 1 charge to activate a spawn of god. Delsgade, is 1000ft by 1000ft and has over 5k hit points. this god cannot attack but grants the user of the crown the ability to only hit critical and deals extra +50cold damage and ignores all immunities.

in the radius of 2000ft around the god all creatures even the summoner must roll a dc 14 constitution saving throw or die in the presence of it. if any entity were do drop to less than 10% of their maximum health in this area they auto mantically die and cannot be revived even using the wish spell. if any entity were to be put to less than 50% of their maximum hp they develop signs of insanity and lose every 2nd go. if they don't recover the lost health or leave the radius of Delsgade within 20 turns they lose all senses and sanity left, forced to become the host of Delsgade and will ultimately bring the undoing of the world as a result.
