wazaa

You release a burst of radiant energy, targeting undead creatures within range. Each undead creature within a 30-foot radius must make a Constitution saving throw or take 3d8 radiant damage. Undead creatures that fail their save are also blinded until the end of their next turn. On a successful save, the target takes half as much damage and is not blinded. This spell is particularly effective against vampires and other undead creatures vulnerable to radiant energy.
