Radiant Cantrip
Once on each of your turns, when you cast a Warmage cantrip that deals Acid, Cold, Fire, Force, Lightning, Poison, or Thunder damage, you can change the damage type to Radiant.
When you deal Radiant damage with a Warmage cantrip, you can reroll one of the cantrip’s damage dice, and you must use the new roll. The number of damage dice you can reroll increases by 1 when you reach Warmage levels 11 (2 dice) and 17 (3 dice).
