Friends through Frostbite - Hypothermia

Mild Hypothermia: You are shivering and your teeth are chattering.

• You have disadvantage of stealth checks.

Moderate Hypothermia: You are shivering uncontrollably.

• You have disadvantage on all D20 rolls aside from frost checks. 
• Your speed is halved
• You have a -2 penalty to your AC and Dexterity saving throws
• You can't use reactions
• On your turn, you can use either an action or a bonus action, not both. Regardless of your abilities or magic items, you can't make more than one melee or ranged attack during your turn.
• If you attempt to cast a spell with a casting time of 1 action, roll a d20. On an 11 or higher, the spell doesn't take effect until your next turn, and you must use your action on that turn to complete the spell. If your can't, the spell is wasted.

Severe Hypothermia: You suffer from frostbite.

• You gain superficial frostbite scars

• You must roll a d10 at the start of each of your turns to determine your behavior for that turn.

  2-6	You don't move or take actions this turn.
  7-8	You use your action to make a melee attack against a randomly determined creature withinyour reach. If there is no creature within your reach, you do nothing this turn.
