League of Legends PBE 9.12 patch notes
Aatrox – Passive cooldown changed from a flat 15 seconds, to 24-12s, lowering as Aatrox levels up. Ultimate bonus healing has been shifted to self-healing only. This will mean Aatrox R will no longer boost summoner heal, redemption or other allied heals.
Ashe – Volley cooldown reduced by 1 second at all levels. Will allow Ashe to poke slightly more throughout the game.
Caitlyn – Base damage up by 2, from 58 to 60.
Karma – Q slow increased from 25% to 35%. Inspire (E) movement speed increased from 1.5 to 2.5 seconds, with mana cost reduced by 10 at all levels. Overall, will allow Karma to better kite and harass opponents throughout all stages of the game.
Lulu – Shield (E) values have been buffed by 10 at all levels and mana cost at later stages reduced by up to 20. Allows Lulu to spam shield with less mana problems.
Sylas – W base heal slightly decreased, however, heal AP ratio has been increased form 0.4 to 0.5. E Shield base values also similarly decreased, but AP ratio up from 0.9 to 1.0. Overall, weakens tank Sylas, but encourages a heavier AP build.
Yuumi – Base health up from 432 to 480. Passive mana refund reduced at earlier levels. W adaptive damage shared between Yuumi and her ally has been changed from 5/9/13/17/21 to 5/7/9/11/13 (+4/7/10/13/16).
Zac – W base damage increased by 10 at all levels. R knock back effect slightly changed from 400 unit from Zac’s center, to 250 units from the target’s current location. R will also drop a single blob on its first target hit (healing thing on the ground).
Corrupting potion – Magic damage burn changed from 15-30 based on level, to a flat 20. Charges reduced from 3, to 2. Health per use increased slightly from 125 to 150. Mana per use increased from 75 to 125. Regeneration of health and mana is now over 15 seconds, up from 12. Overall, a large hit to corrupting pot, with reduced, and slower healing + mana regen.
