Consumable
Medium Stamina Mead
Restores stamina.
Medium Stamina Mead is a Plains-tier consumable fermented from 
Mead Base: Medium Stamina, a base mixed at the mead ketill that yields six bottles after two in-game days. Drinking one restores 160 stamina over two seconds and starts a two minute cooldown that blocks every stamina mead, including 
Minor Stamina Mead. Jotun's Chests in Mörkhalla also hold it.
