Riot Games has deployed minor changes to the League of Legends live server. Three champions received changes in this mid-patch 10.18 update: Ahri, Kayle, and Zac.
The change that affects Kayle's E is not a mid-patch adjustment. It's been available since the patch was released, but the team forgot to mention it in the patch notes!
E - Starfire Spellblade
Cooldown decreased: 8 seconds → 8 / 7.5 / 7 / 6.5 / 6 seconds
Z - Unstable matter
Bug Fix: Fixed a bug where Zac's cooldowns were not properly reduced when picking up Cell Division pieces.
Bug Fix: Fixed an issue where Ahri's W - Foxfire would not correctly assign the three shots based on the new targeting priority from 10.18
This patch also fixed an issue where in-game announcements would not display correctly for champions with Mastery of 4 or higher.
On top of these changes, Riot Games introduced a new mechanic allowing players to display the name of the champion instead of the player's nickname. Meaning you can now hide the names of any player in your games and replace it by the name of the champion just like you could just hide everything.
Back from a week of Holidays Riot Games delivered Patch 10.16b while more testing is being done with 10.18 on PBE. No patch 10.17 this time as this version will be skipped.
