A pair of gloves, each pulsing with a magical energy. The right glove radiates with heat and the left radiates with cold.

When the user wields the gloves, they can channel the energy of the gloves into their unarmed strikes.

When wearing these gloves you can add either +2 fire damage or +2 cold damage to your unarmed strikes.

Fire and Ice Points

At 1st level, you acquire the ability to create ice with one side of your body and fire with the other. You are able to use these abilities through your fire and ice points, which are determined by your level in this class. The number of points you have is tracked Fire/Ice points column of the Thermo Gloves table. You regain your maximum fire and ice points at the end of a long rest.

You use these points to fuel your various fire and ice abilities. You start knowing four such abilities Freezing Ground, Icy Touch, Burning Defense, and Heating Grasp.

Some of your fire and ice abilities require your target to make a saving throw to resist the feature's effect. The saving throw DC equals 8 + your proficiency modifier + your dexterity modifier.

Freezing Ground - As an action, you expend 1 ice point to cover up to a 30 foot radius area around you in ice. This area becomes difficult terrain and creatures caught within this area must make Dexterity saving throw against your fire/ice DC. If the creature fails, they fall prone. If they succeed, they maintain their balance. You are immune to the effects of this terrain. The ice will melt after 1 minute or it can be melted by your heat as a bonus action.

Icy Touch - As an action, you expend 1 ice point and touch a creature of your size or smaller. The creature must make a Dexterity saving throw against your fire/ice DC. If the creature succeeds, nothing happens. On a failure, they are restrained by ice that forms along one of their appendages. The creature can attempt to break the ice as an action by making a Strength saving throw against your fire/ice DC at the start of each of their turns. You can melt the ice as a bonus action.

Burning Defense - As a bonus action, you expend 1 fire point and gain the following benefits. You cover half your body in fire and increase your AC by 2 for 5 minutes. You can dismiss this fire as a bonus action.

Heating Grasp - As a bonus action, you expend 1 fire point and heat up the weapon you are holding. Your next attack with that weapon deals an additional 1d4 fire damage.
