Eadric's Enchanted Emissary

You spend an hour weaving together several spells into one enchanted messenger. You must fill the obsidian chest with whatever goods need delivered before the spell is cast. During the ritual you must clearly state the recipient's name and the date, time and location where the goods must be delivered. The date can be for anytime in the future however if the creature or location where the goods must be delivered is not currently upon the same plane of existence the spell does not work, however the materials are not used up if it fails. Upon a successful cast, the messenger takes on the statistics of Animated Armor places the chest within it's armour and immediately sets off at a fast pace towards it's destination. During this time it is immune to all damage however remains vulnerable to dispel magic. The chest is trapped with a fireball spell and only the combination/key phrase can disarm this upon opening. Should the messenger find itself in a situation where it cannot continue the delivery, it will activate the trap and destroy itself and the contents of the chest. Upon successful delivery, the armor clatters to the ground and becomes unenchanted.
