Crafted food and camp objects cover your leveling buffs, and neither replaces a raid flask.
- Crafted food still grants combat stats plus a small XP bonus while leveling.
- A Basic Campfire is a place to sit and refresh food buffs.
- Sharpening Wheel, Faction Banner and Incense Candle are camp buffs. They do not stack with the matching class buff.
- Incense Candle is a camp object, not a food recipe.
Unconfirmed recipe names, flask names and ranks, and whether camps work inside instances.
