Oath of Winter

Often seen as cold hearted, intimidating, and cruel, the Oath of Winter Paladins are, in reality, unyielding in their morals, unstoppable in their fury, and unrestrained in their passion and love for the natural beauty of the world. Their tenets are as follows:

Cold of Heart. Winter is uncaring. Do not let emotion corrupt you, or sway you from your convictions.

Pure as Snow. Winter is unstained. Frost strips the world bare, leaving only what is true. Burn away deception and corruption until only truth remains.

Protect the Cycle. Winter is death, making life dormant until the start of the next cycle of nature. Maintain the Cycle of Life by helping others grieve and preserving the natural, the young, and the weak from forces unnatural that seeks to harm them.

Channel Divinity

Killer Frost. As an action, you present your holy symbol and sear a creature you can touch with killing frost. The target must make Constitution saving throw.

On a failure: It takes 1d6 cold damage + 1d6 necrotic damage It is afflicted with a Freezer Burn effect for 1 minute. On a success: it takes half damage and no effect.

Phase 1: Winter is coming. At the start of each of its turns, the target takes 1d6 cold + 1d6 necrotic damage. If it takes cold damage, the effect flares, taking an extra 1d10 necrotic damage (once per round). It's speed is reduced by 10ft every time it takes cold damage. The creature can repeat the saving throw at the end of each of its turns, ending the effect on a success.

Phase 2: Feel the chill of despair. Ice takes over the body. After 2 failed saving throw, the target loses its resistance to cold damage and takes additional damge equal to your proficiency bonus when hit with cold damage from the paladin and from a source other than Killer Frost. The target also has disadvantage to Constitution saving throw.

Phase 3: The Winter takes it all. After 2 more failed saving throw, the target is frozen for a number of hours equal to your proficiency bonus.
