Shows your current Ignite damage and the time left of the Ignite dot in a clean, uncluttered way. Ignition does not predict the incoming Ignite, other addons will do that but until the predictions become more reliable a mage's best option is to look for multiple crits in a row to build a big Ignite dot.
To move Ignition, use ctrl-click to drag the panel around your screen.
