Alchemical Delivery: This Flask can be filled with any type of liquid.  As a Bonus Action you can speak a command word to activate the flask.  When you do, the flask spreads its wings and flies to a creature of your choice within 120 ft of you.  when it arrives, it opens itself and pours the contents into the mouth of the creature.  It automatically fails to administer the liquid to a creature unwilling to drink it.  After administering the liquid, the wings fold back into the flask nd it drops to the group.  the flask can be used again one hour after it has been activated.
