Deploy Armor

 Your armor is able to be donned or doffed near-instantly.  Your armor can be stored when not used in a compact form, roughly the size of a canteen, including any integrated shield and special weapon.  As a bonus action, you can grab the armor and instantly deploy it, covering you completely with any weapons available.  Alternatively, as a ritual casting, you can prepare and deploy the armor more slowly, over one minute (thirty seconds preparing the armor, and thirty seconds for the activation effect).

Depending on the style you've chosen for your artificer, the effect could be a flash of light leaving the armor as it fades; a shadow falling over you and thickening into the armor; the armor expanding over your body like molten metal; the armor unfolding and deploying the like multi-dimensional clockwork; or an effect of your own choice.

The can be returned to compact size using another casting of the spell, or as a ritual.
