Consumable
Frost Resistance Mead
Protects against the cold.
Frost Resistance Mead is a Swamp-tier consumable fermented from 
Mead Base: Frost Resistance, which is brewed in a mead ketill. Two in-game days of fermenting yield six bottles, and they stack to 10. It grants frost resistance for 600 seconds, which prevents the Cold and Freezing effects outright and reduces incoming frost damage for as long as it runs.
