Thermal Touch

Touch a creature or object and sharply raise or lower its surface temperature. Make a melee power attack. On a hit, the target takes 1d8 fire or cold damage. Unattended mundane objects may become hot, chilled, brittle, fogged, or thawed.

Temper

Warm or cool one willing creature, held object, drink, meal, tool, weapon, garment, or small area you touch. The target remains comfortably warm or cool in ordinary weather and has advantage on the next save against mundane heat or cold before the duration ends.

Heat Lash

Whip a line of concentrated heat at one creature or object within range. Make a ranged power attack. On a hit, the target takes 2d8 fire damage, and the next time it takes cold damage before your next turn, add your CHA modifier to that cold damage.

Cold Pinch

Pull heat away from one creature or object within range. The target must make a CON save, taking 2d6 cold damage and having its speed reduced by 10 ft. until the start of your next turn on a failed save, or half damage only on a success.

Comfort Field

Regulate the temperature in the emanation. Chosen creatures ignore mundane extreme heat and cold, and food, water, ink, tools, bedrolls, and simple supplies in the area are protected from freezing, overheating, spoiling from heat, or becoming painfully hot or cold.

Thermal Read

You sense temperature gradients, body heat, cold spots, drafts, recent fires, warm footprints, cooling blood, active machinery, hidden vents, and thermal traces within 60 ft. This does not see through total cover but can reveal heat leaking through thin barriers.

Heat Sink

Create a 10-ft. radius heat-drain centered within range. The area becomes cold difficult terrain. A creature that enters for the first time on a turn or starts there must make a CON save, taking 3d8 cold damage and having its speed reduced by 10 ft. on a failed save, or half damage only on a success.

Heat Bloom

Cause air, metal, stone, water, or skin at a point within range to bloom with heat in a 10-ft. radius sphere. Creatures in the area must make a DEX save, taking 4d8 fire damage on a failed save, or half on a success. Unattended ice, frost, wax, or thin metal may melt or warp.

Insulating Skin

Touch one willing creature. For the duration, the target has resistance to either fire or cold damage, chosen when you use this power. The target also ignores mundane extreme heat or cold of the opposite type for the duration.

Steamflash

When fire or cold damage is dealt within range, convert the temperature swing into blinding vapor, frost fog, or heat haze. A 10-ft. radius sphere centered on the damaged target becomes heavily obscured until the start of your next turn. One creature in the area must make a CON save or be blinded until then.

Heat Death Pulse

Rip heat out of the area and release it again as a violent pulse. Creatures of your choice in the emanation must make a CON save, taking 5d6 cold damage and 5d6 fire damage on a failed save, or half on a success. Objects may crack, fog, sweat, frost, or smoke.

Thermal Updraft

Manipulate warm and cold air currents around yourself. Gain a fly speed of 30 ft. while outdoors, in a large chamber, or anywhere air can circulate. If the effect ends while airborne, you descend safely up to 60 ft. before falling.
