Sun Blessed

You know the Sacred Flame cantrip. This does not count toward your maximum number of cantrips. Constitution is your spell casting modifier for this spell.

Once per long rest, if you are the target of a melee or spell attack that you can see, and the attack requires line of sight, you may use your reaction to give the attack disadvantage, but only before you know if it hits or not. You may continue to use this effect until it causes an attack to miss. 

If you are in direct sunlight continuously for at least one hour, you may choose to emit light for 5ft and dim light for a further 10ft, for up to 10 hours. This is a free action.
