User blog comment:Degritone/Degritone's Sion-Level rework for Yorick/@comment-24420226-20160210171440/@comment-25364408-20160210182928

It was instant at first, then I thought about how something twice sight range + 100 is a little large to just be instant. A cast time would be uncancelable beyond death, however, and as I said, all numbers can be changed. The way I imagine making a giant arena of no escape would be used is by hiding just out of sight and using it for surprise 300 damage. Though, 2.5 is a bit long, I guess. I just wanted to be on the safe side with it. How about 1 second cast time, similar to Ez ult?
