After the vision changes of patch 6.7 Karthus' (W) no longer grants vision surrounding the pillars of the wall of pain. There have been no mentions of this change in any recent patch notes so I assume this is unintentional.

blackcat13001 votesunlikely all the patch thus far have ignored or nerffed Karthus sorry but with him being excluded from the immobile mid mage update and getting his wall neffed I don't see the wall bug getting fixed or the cast speed of his Q in death defied getting fixed either.
