Hypnio-osis is a form of speaking or influencing another without using vocal commands. While it can possibly be practiced, it is most often a trait a dragon is born with. Some examples would be Nonkee the Overachiever, who used this influence to make the crowds he performed for find him much more enthralling than he possibly was. The dragon known as Comet uses a form of this to control some sea creatures, most notably the kricklecrab known as Bubbles. Kaida is said to have possible soothing powers while utilizing this, Jade has experienced something he attributed to this deep in the Sea of Vatten, and more. While it has not been proven to actually exist, others swear by its influential powers.
