Each Chant has a trigger condition which ends it prematurely (although one chant, Song of Purification, can be triggered multiple times before it ends).

Chants can have either an Energy or an Adrenaline cost, and have a one or two second Activation Time.
Chants also trigger the leadership attribute effect, granting the Paragon one energy for each Ally affected by a Chant, up to a maximum of 1 energy per 2 points of Leadership for each Chant activation.
It is important to differentiate between Shouts and Chants. The most important distinction is that Chants have an activation time and thus can be interrupted.

Instead, chant activation can be identified by the glowing wings animation that appears behind the paragon during activation.
