Thermokinesis

You can instantly heat or cool an object or surface you are touching which is no larger than 5 feet in any dimension. You may cool a bowl of food, heat the water in a bath, or even just make your hand warmer for a snug handshake. When you do so, the object does not become hot or cold enough to cause damage to a creature.

Alternatively, you may cast the spell over the course of 1 minute to significantly raise or lower the ambient temperature in a 20-foot-radius sphere, centred on you, causing it to become an area of extreme heat or extreme cold, or making the temperature hospitable. If you cause an extreme of temperature, any water in the area either steams like a sauna, or ices over as appropriate for the conditions. The DM decides what other effects may occur as a result.

If you choose to end the spell early, or if you lose concentration before the spell is complete, the temperature is still raised or lowered, but does not reach an extreme.

When the spell ends, the temperature begins to return to normal, happening instantly if the space is in the open, or over the course of 1 minute for every minute you spent concentrating on the spell (maximum 1 hour) if the area is enclosed.
