You have resistance to necrotic damage and radiant damage.

Starting at 3rd level, you can use your action to unleash the divine energy within yourself, causing a searing light to radiate from you, pour out of your eyes and mouth, and threaten to char you.
Your transformation lasts for 1 minute or until you end it as a bonus action. During it, you shed bright light in a 10-foot radius and dim light for an additional 10 feet, and at the end of each of your turns, you and each creature within 10 feet of you take radiant damage equal to half your level (rounded up). In addition, once on each of your turns, you can deal extra radiant damage to one target when you deal damage to it with an attack or a spell. The extra radiant damage equals your level.
Once you use this trait, you can't use it again until you finish a long rest.

Your Constitution increases by 2, and Charisma score increases by 1.

 A typical construct body may run for thousands of years if maintained properly. The maximum lifespan remains a mystery; so far, divine constructs have shown no signs of deterioration due to age. You are immune to magical aging effects.

Your size is Medium.

Your base walking speed is 30 feet.

You were created to have remarkable fortitude, represented by the following benefits:

You have advantage on saving throws against being poisoned, and you have resistance to poison damage.
You don’t need to eat, drink, or breathe.
You are immune to disease.
You don’t need to sleep, and magic can’t put you to sleep.

When you take a long rest, you must spend at least six hours in an inactive, motionless state, rather than sleeping. In this state, you appear inert, but it doesn’t render you unconscious, and you can see and hear as normal.

You can speak, read, and write Common and one other language of your choice.
