Consecrated Earth

With a furious shout, you consecrate the earth around you. The earth is infused with crackling holy energy in a 20 foot radius centered on you and moving with you. Any enemy caught within this radius as the spell is cast must make a Constitution saving throw, taking 1d8 radiant damage on a failure or half as much on a success. Any enemy who starts their turn in this area or moves into it for the first time on their turn takes 1d4 radiant damage. Friends and Undead instead take 2d8 radiant damage from the initial burst and 2d4 radiant damage from the ensuing effect.
