Heat Extinguishment
By mastering Reverse Cursed Technique and your primary ability, you have inverted your control over flames into the power to extinguish and nullify them, even affecting the heat within living beings.
As an action or reaction to being targeted by a cursed technique AOE that deals fire damage, you can spend 2 cursed energy to extinguish a 10 feet cube of flames within 30 feet where the technique is nullified. If the technique is an attack roll, you can spend 2 CE as a reaction to reduce the fire damage by 6d8. If an attack’s damage is reduced to 0, any additional effects of the attack are canceled out.
Hypothermic Touch. At 3rd level, as an action you can spend an amount of cursed energy up to twice your CE modifier to make a melee attack roll and extinguish the heat within a target’s body. The target must succeed on a Constitution saving throw or take 2d8 cold damage per cursed energy spent. On a success, they take half as much damage.
If they fail by 5 or more, their movement is reduced to 0 until the end of their turn.
This reversal does not affect creatures that do not rely on body heat or are immune to cold damage.
