I’ve seen a lot of new players wondering if Diana’s Orbs hit multiple targets.
Diana’s Orbs no longer hit multiple targets
Currently, they DON’T. As of Patch 9.23 released by Riot on Nov 20, Diana’s Orbs can hit only one target. Previously, in Patch 9.22, they could hit multiple targets, but this wasn’t intended. It was actually a bug, that made her very strong, some Challenger players even considered her an S-tier pick.
But in patch 9.23, this bug was fixed, this being considered a huge nerf to her, transforming her into an above-average pick, so we expect to see her less in the current meta.
