League of Legends 9.12 PBE: New Balance Changes to Sylas, Ryze, Updates to Mordekaiser And More

UPDATE: New changes in 9.12 PBE have arrived: League of Legends 9.12 PBE Balance Changes: New Ryze Changes, Tentative Tweaks on Sylas

The latest updates on 9.12 PBE include more tweaks for Sylas, some changes to Mordekaiser and the highlight this week is Ryze, which will probably get a lot more changes tomorrow, as noted by Riot Repertoir in his Twitter posts.

But before we see the latest balance changes in the League of Legends Public Beta Environment, let’s see what the latest mid-patch update brings.

You might have probably noticed the official patch notes for patch 9.11 that were released this week to the live servers. Then Karthus, Master Yi and Vayne got a mid-patch update, buffing the first two and fixing a bug for Vayne:

Karthus – R – Requiem: AP increased to 75% (from 65%)

Master Yi – Q – Alpha Strike: increased to 25% attack damage per additional strike (from 15%)

Vayne: Bugfix – R – Final Hour:no longer removes the movement speed granted from her Passive – Night Hunter”

Now let’s check out the balance changes in PBE 9.12.


The reworked Mordekaiser is getting a couple of tooltip updates on his passive and W.

  • Passive – Darkness Rise

[Tooltip update] “Darkness Rise can activate on Epic monsters. Aura/speed has a 5s duration and is refreshed with each champion attack or spell hit.”

  • W – Indestructible

Potential shield values separated, now they are: 30% of damage he deals and 15% of damage he takes

[Tooltip update] “Shield value decays over time. Damage stored by non-champion sources reduced by 75%. Minimum Shield: 5% maximum health / Maximum Shield: 30% maximum health.”

Sylas – NERFED

Apart from the changes we’ve seen here, Sylas gets more tweaks:

  • Passive – Petricite Burst

Damage reduction to other targets than the primary one is lowered to 30% (from 50%)

However, he now has 2 charges!

  • Q – Chain Lash

The explosion damage from the intersection point is lowered to 40/60/80/100/120 (from 45/70/95/120/145), and so is the AP ratio – to 40% (from 60%)

  • E – Abscond / Abduct

Ryze is a bit more complicated, since it has various changes that will probably need more testing, as Riot Repertoir mentioned that:

There will likely be a pretty different one [changelist] on Monday that is less… drastic.

He also noted in his Twitter post that they are “trying two different things out before deciding on the right blend of the two for 9.12,” and he is waiting for feedback on the current changes from players. Here are the current changes in 9.12 PBE, according to his changelist:
