The ult reveals for a shorter time than Tf's ult, and while the damage is higher than Karthus' ult, it is damage over time that is relatively easy to avoid.

And what about the anchor? It reveals the area around it and is the source of new Illumination Bolt's after it is placed. It is then "moved" with each Illumination Bolt cast.
