The Storm Shield was a buff granted for capturing a marked control point on the Crystal Scar. It was removed with the removal of Dominion on Patch 6.4.
- This buff was not transferable and was simply lost upon death.
- To acquire this buff, champions had to channel for three seconds onto a Greater Relic without taking any damage which would re-appear after 3 minutes.
- This buff can be identified by swirling blue relics around the champion who possesses it.
- Before Patch 18.104.22.168, there existed that would instantly kill Karthus twice (Double Kill) if Lightning's damage was used to trigger Leona's Sunlight.
