Forgeguard Furnace Vent

Your own barriers build up to 100 Forge Heat as they absorb damage: absorbing 1% of your maximum health grants 1 heat. At 25 or more heat, your next Furnace Vent spends it all on bonus damage shared among up to 5 nearby enemies, totaling up to 25% of maximum health at 100 heat.
