When you roll initiative, gain Frost Armor: Roll STR saves with advantage. Reduce all Primary Dice rolled against you by 1 and Chill the attacker if they miss if adjacent. Ends when the encounter does, or when you hit you may end it to add 1d20 damage to an attack instead.

Your unarmed strikes deal 1d6+STR damage and Chill on crit. Roll your Frost Armor die with advantage.

Gain Frost Armor the first time you would gain a Wound each encounter.

When you use Infuse Strength, your target gains Frost Armor.

Regain Frost Armor whenever you use a Burst of Speed.
