Dawn of the Everlight

You radiate a 30-foot aura of brilliant coloured daylight which fills the area within range and moves
with you. The colour is determined by the consumed gemstone. The aura has the following effects:

• Any darkness spell of 6 th level or lower within the area is dispelled, and new such darkness
  spells cannot take effect within the area.
• All invisibility effects are dispelled, and creatures have disadvantage on Dexterity (Stealth)
  checks.
• Creatures with darkvision within the area at the time of casting are blinded until the start of
  your next turn unless they make a successful Dexterity saving throw. If you warn your allies
  before casting, they may use their reaction to avert their eyes to negate this effect.
• Up to 6 creatures of your choice within the area gain the benefits of the bless spell while
  they remain within the area. If a recipient of this benefit leaves the area and returns later,
  the benefit resumes.
• Undead creatures within the area at the start of their turn take 6d6 radiant damage and are
  frightened of you unless they make a successful Wisdom saving throw. On a success, the
  damage is reduced to half and they’re not frightened. A creature frightened by this spell can
  attempt another saving throw each time they end their turn outside the spell's radiu

At higher levels: When you cast this spell using a spell slot of 7 th level or higher, its radius increases
by 10 feet and undead creatures take 1d6 additional radiant damage per slot level above 6 th .
