Radiant Inferno

Your inner light burns with greater intensity, setting nearby creatures and objects ablaze.

While radiant consumption is active you gain the following:

• You have resistance to fire damage.
• You ignore other creatures' resistance to radiant and fire damage.
• When you deal fire damage, you can choose to deal radiant damage instead and vice versa.
• Any area of magical darkness that overlaps with the area of bright light created by radiant consumption is dispelled.
• The radiant damage you deal and receive at the end of your turn increases by 1d4.
  This additional damage increases to 1d6 at 7th level, 1d8 at 11th level and 1d10 at 17th level.
• Flammable objects within 10 feet of you that aren't being worn or carried are ignited.
