Some changes will be coming to experience bottles very soon. As of today, all existing xp bottles and bank notes will stop working. The bottles are being converted to store raw experience instead of levels. Existing non-functional bottles may be exchanged with me for 11 experience per level. Bank note and new experience bottle functionality will return when the experience bottles are updated. Existing bottles will not work now or post-update. If you die, you will still lose all experience in your experience bar. We apologize for the inconvenience. UPDATE: XP Bottles are back with the new mechanics. Throwing old bottles automatically gives you the appropriate trade-in value.
