Forge Sense

Forge Sense. You can unerringly estimate the intensity of heat sources within 30 feet of you (e.g. the amount of fire damage a fire elemental could cause, the fire damage of a cast spell, the damage potential of a blazing bonfire, etc). When you deem it necessary, you can use your reaction to intone a protective prayer and give resistance to fire damage to a creature or object within this range. You regain this reaction after finishing a short rest.
