This is a Rage Power option.
Prerequisite: Have not previously chosen the Raging Inferno (Rage Power).
- When you rage, your skin becomes icy and cold to the touch. You gain resistance to cold damage, and can't have an AL below 17. Taking heat damage removes this effect until the start of your next turn.
- Once on each of your turns while you're raging, you can release a burst of sheer cold when you hit a target with a melee weapon attack. When you do, that target takes an extra 1d4 cold damage per point of proficiency bonus you have.
- When a creature takes cold damage in this way, its speed is reduced by 3 meters until the start of your next turn.
