[Exploit] Use food/pots from your guildbank
2 exploits using bank / guildbank
Place food/pots in bank but make sure there is a place on one of your bars to click on and run off and quest. I save myself 5 bag spaces doing this.
Also if you drag resource items from your bag onto an item in your bank it puts the item in the resource section of your bag! More storage space. You can do this with quest bag aswell!!
