Hoarfrost Knight

Hoarfrost knights watch over the frozen tundras, using blade and magic to protect them. Some of these knights serve Gods of Winter, such as Auril or Thrym; others serve nobody, taking it upon themselves to protect their own lands.

Icy Blade

3rd-level Hoarfrost Knight feature

You can create weapons of ice from thin air. As a bonus action, you can create an icy blade in a free hand. This blade is a simple melee weapon with the finesse property. On a hit, it deals slashing damage equal to 1d8 plus the ability modifier you used for the attack roll. The blade's attacks count as magical for the purpose of overcoming resistance and immunity.

Once per turn, when you hit with your icy blade, you can deal an additional 1d4 cold damage to the target. You can do this a number of times equal to your proficiency bonus, and regain all expended uses on a short or long rest. When you reach certain levels in this class, the size of this damage die increases: at 5th level (1d6), 11th level (1d8), and 17th level (1d10).

Frost Magic

3rd-level Hoarfrost Knight feature

You learn an additional spell when you reach certain levels in this class, as shown in the Frost Magic Spells table. You can cast each spell once per long rest, using your Wisdom as your spellcasting ability. You also learn the ray of frost cantrip.
