We've seen adjustments to a number of League of Legends rune systems this season, but in next week's Patch 14.13, developers at Riot Games are specifically targeting Domination Keystones, with the ultimate goal of blurring the lines between the two systems.

League's lead gameplay designer Matt "Phroxzon" Leung-Harrison outlined the developer's plans to make each Domination Keystone more unique in his Patch 14.13 preview on X (formerly Twitter) on June 17. "We're trying to differentiate between Electrocute and Dark Harvest," he said, specifically looking to transform Electrocute into an early-game option by reducing its cooldown and increasing its damage.
On the other hand, Dark Harvest will provide a much less flat damage boost and reward players for building up harvest stacks, which will be made much easier thanks to a cooldown decrease in Patch 14.13. “There is a stretch goal to make Dark Harvest better for laning champions by reducing the cooldown so it can stack faster,” Phroxzon said, adding that champions who rely most on Dark Harvest will also be looked at this week.
In total, 17 champions will see adjustments next week. The majority of Dark Harvest regulars, such as Karthus, Kennen, and Taliyah, are in line for nerfs at this stage. But Phroxzon said that he and the team were “trying to be a little bit more risk averse” with champions surrounding these keystone adjustments. If they’re successful, we can expect more adjustments in the coming weeks.
