Patch History

V9.23 - Added

• Replaces Kleptomancy.
• Inspiration Keystone rune.
  • Periodically gain a single use of another random keystone. Once a keystone is rolled, it can't be rolled again until only three options are left, at which point the table resets (you won't get the keystone you just used, though).
  • Gain a new keystone 8 − 4 (based on level) seconds after using the last (12 − 8 (based on level) seconds for ranged champions). Scaling is weighted toward later levels.
  • Gain a new keystone while out of combat after 40 seconds of not using a keystone.
  • Your current keystone shows up to the right of your health bar. All ten players can see it.
  • Dark Harvest souls persist after you get a different keystone and affect all your other keystones. Grasp of the Undying's health persists after you get a different keystone, too.
  • Available Keystones: Press the Attack, Lethal Tempo, Fleet Footwork, Conqueror, Summon Aery, Arcane Comet, Phase Rush, Electrocute, Predator, Dark Harvest, Hail of Blades, Grasp of the Undying, Aftershock, and Glacial Augment.
  • Predator is only available to champions who have already purchased boots. Dark Harvest souls amplify the effects of all keystones. Aftershock is only available to champions who have learned a basic spell that can trigger it.
  • Does not re-roll if in-combat.
  • Keystones cycle pseudo randomly - you cannot repeat a keystone for 5 rolls after it has been used.
  • Entering the fountain will reroll your current keystone.
