Blade of Light

You conjure a blade of light in your hand that gives off bright light in a 20-ft radius. The blade can take the form of any 1-handed sword or dagger (caster's choice and design) and treat it as a +1 version of the weapon dealing radiant damage instead of its normal damage type.. When used against Demons, Devils, or Undead, the blade's magical enhancement increases to a +2.

At Higher Levels: When you cast blade of light using a spell slot of 4th level or higher, the enhancement increases to +2, +3 vs evil creatures. At 6th level, the enhancement increases to +3, and when used against evil creature lands a critical hit on a roll of 19 or 20.
