School of Cryomancy

Wizard that majored in the school of Cryomancy thought there was very little Ice spells and decided to try and make their own. One who is proficient in fire techniques goes by Pyromancer, one who studies earth magic may be known as a Geomancer, and one who studies holy or undead techniques are referred to as Photomancer and Necromancer respectively. Though, a wizard who specializes in ice magic is known as a Cryomancers. Also known as Frost Mages, Cryomancers manipulate the crystalline structure of ice and bend it to their will. They're known for being able to freeze water, even the moisture in the air, to create ice for their disposal. Normally known as utility and defensive magic, Cryomancy is no stranger to being devastatingly powerful.

Cold Savant

When you choose this school at 2nd level, the gold and time required to copy ice-themed spells is halved.

Ice Sculpting

Beginning at 2nd level, if you cast a AOE spell that deals cold damage, you can choose up to 1d4 creatures and any damage they would've taken is reduced to 0 damage.

Cryo's Past

Beginning at 6th level, you gain the power of past cryomancers within your spell book. You choose up to 2 spells that can deal cold damage.

Perfect Preservation

Beginning at 10th level, you gain resistance to cold damage. Additionally, if a spell, such as resurrection, that has the sole effect of restoring you to life (but not undeath), the caster doesn't need material components to cast the spell on you. Additionally, your body is always under the effects of the gentle repose spell. 

Zero Ice-Contact

Beginning at 14th level,  your ice approaches absolute zero and even momentary contact can be deadly. If you cast an ice spell where a saving throw is required and a creature succeeds their saving throw, the damage is not reduced but any condition that would be afflicted isn't.
