The Cozy Sleeping Bag is a reusable item in WoW Forever that gives you a small experience bonus and counts as a rested area while you use it. Blizzard hasn't written it up. Everything below is reported by players and guide sites, chiefly Warcraft Tavern.
What it does
Reported:
- A Well-Rested buff of 1% more experience per stack, up to 3 stacks, one stack a minute.
- Counts as a rested area, like an inn.
- One-hour cooldown, and anyone in your party can use it.
- Stacks with camp and food buffs.
How to get it
Reported: it's the reward of a quest chain that starts around level 14 and sends you through Westfall, the Barrens, Stonetalon Mountains, Loch Modan and Hillsbrad Foothills. Horde players do the same zones in a different order. Pick it up early, since 3% on every kill adds up over 60 levels.
How it fits with the rest
The sleeping bag is one of several Forever extras for leveling. See rested XP for how they stack, the camping system for campfires and the Camp Tent, and the Pouch of Violet Dust for the Twitch drop that runs until 12 November.
