Bard fires a missile which will slow the first enemy struck, and continue onward. If it strikes a wall, it will stun the initial target; if it strikes another enemy, it will stun them both.
Reveals a healing shrine which powers up over a short time, disappearing after healing the first ally that touches it.
Bard opens a portal in nearby terrain. Allies and enemies alike can take a one-way trip through that terrain by moving into the portal.
Bard sends spirit energy arcing to a location, putting all champions, minions, monsters, and turrets hit into stasis for a brief time.
Bard travels through realms beyond the imagination of mortal beings. Some of Valoran's greatest scholars have spent their lives trying to understand the mysteries he embodies. This enigmatic spirit has been given many names throughout the history of Valoran, but titles such as Cosmic Vagabond and Great Caretaker only capture a fleeting aspect of his true purpose. When the unknowable structure of the universe is threatened, Bard steers all existence away from utter annihilation.
