Ultimate Spellbook Changes

One for All-timate Spellbook

  • Chances adjusted, now more likely to happen

Ultimate Updates

  • The following ultimates have been updated to match their original champion's functionality:
    • Caitlyn R
    • Kai'Sa R
    • Maokai R

Bugfixes

  • Fixed several missing translations in Ult-ernate Summoner Spell tooltips
  • Mordekaiser R will now properly remove the champion icon of an enemy next to your health bar when they have respawned.
  • All Ult-ernate Summoner Spells will now consistently trigger the champions channeling animation rather than sometimes using their normal ultimate animation (this would be confusing on certain champions like Wukong)
  • Fixed several spell status icons that were previously missing

Competitive Changes

Summoner's Rift Ranked queue matchmaking now focuses more on the players' MMR and less on their actual visible rank.

QoL Changes

  • Addressed some high variation between the milestones for some Starter Series Eternals (e.g. the “Epic Monsters Killed” milestone 1 would require Amumu to kill 9, Diana to kill 3, and Fiddlesticks to kill 2). Values to reach this and other milestones have been updated to be more uniform across champions. (Note: this was updated in patch 12.16, but was not included in the patch notes.)
  • Updated tooltips on champions that can swap between melee and ranged forms (e.g. Jayce or Nidalee) so that they now dynamically update values based on whether they are in melee or ranged form.

Bugfixes

  • Fixed a bug that would cause the cursor to move erratically when using smart pings.
  • Fixed a bug that caused the Ancient Grudge Buff (which reduces damage done to subsequent drakes) to not grant damage reduction for every Drake slain if the Drakes were Hextech ones.
  • Fixed a bug that caused Draven’s R execute passive to still execute enemies through spellshields.
  • Fixed a bug where Rift Herald’s spawn animation would interrupt the knockback from Poppy’s R.
  • Fixed a bug that caused Ornn’s item upgrades to be lost if the teammate he was upgrading died during the channel.
  • Fixed a bug that caused Sejuani’s E to proc Tear of the Goddess stacks when a melee champion would walk near her.
  • Fixed a bug that removed Fizz’s E range indicator to not show after his VFX update.
  • Fixed a bug that caused Zeri’s Q animation to leave vision for longer than intended when last hitting minions.
  • Fixed a bug that caused Pyke’ R to go on cooldown if the enemy was killed by another ally.
  • Fixed a bug where champions could cast Flash while Charmed if they casted Heal or Ghost.
  • Fixed a bug where the Treasure Hunter rune would play Draven’s passive sound effects if there was a Draven present in the game.
  • Fixed a bug where executing to the Fountain or minions would progress the “Free Ticket to Base” challenge.
  • Fixed a bug where Sion’s Zombie form would count as an additional kill or assist for certain challenges.
  • Fixed a bug where Sett’s ultimate would disable opponent’s Hexflash and Flash for the remainder of the game.
  • Fixed a bug that would cause Unleashed Teleport’s cooldown to display incorrectly on the scoreboard once it has transformed.
  • Fixed a bug where using certain abilities after casting Flash would disable Hexflash and Flash.
  • Fixed a bug that gave Elder Dragon the normal Drake roar as opposed to his own, special, Elder roar.
