Many of these will likely be hotfixed to live as part of the 12.23b patch. Some may be held until next year instead for the 13.1 patch.

Note that many changes cannot be easily datamined, such as functionality changes, bugfixes, or mode-specific balance modifiers.

edit: Nilah R healing is complicated, since it also applies her Q healing, so what I previously listed as a straight nerf is actually a late game buff since the Q healing buff offsets it.

 

Changes from today:

Champions:

Hecarim:

• Q per stack damage amp:  4% +5%% bAD  -->  3% +4%% bAD
  • max at 3 stacks:  12% +15%% bAD  -->  9% +12%% bAD

Lillia:

• P base target tHP scaling over 3s:  6% --> 5%
• Q base damage:  40-80 --> 35-75
  • reminder:  outer radius applies the same value again as true damage
  • this is a further nerf to what was already applied on 12.23

Lux:

• E damage AP scaling:  70% --> 80%
• R damage AP scaling:  100% --> 120%

Mordekaiser:

• P can no longer gain stacks from small monsters through spells (12.23 changes only affected attacks)
• W pre-mitigation damage taken to shield generation:  15% --> 10%
  • reminder:  non-champions are 25% of these values
  • note:  due a bug, these values are actually 50% effective, so the real change is 7.5% --> 5%

  • active damage tAD scaling:  90%-130% --> 90%-120%
  • active damage crit amplifier:  100% crit chance --> 120% crit chance

• R:
  • damage bAD scaling per minor tick:  35% --> 28%
    • for all four minor ticks:  140% --> 112%
    • reminder:  after these four ticks, a fifth tick deals larger damage, which is currently unchanged
  • champion damage dealt to healing conversion:  30% +15%% crit chance  -->  20% +30%% crit chance
    • reminder:  non-champions are always 10% of damage dealt

Rammus:

• W base armor:  50 --> 40
• W base magic resist:  15 --> 10
• W cooldown:  6s --> 7s
  • the resists change is a full revert of the 12.22 hotfix, with this new cooldown nerf added on

Vex:

• some passive icons hooked up? not sure what this is supposed to fix, maybe some buffs had missing icons
  • confirmed now, her passive buff icons are empty on live, fixed on pbe, thanks for the info everyone

Zed:

• Q base damage:  80-220 --> 70-210
• E base damage:  70-150 --> 65-145

Ravenous Hydra:

• stacks lost on death:  50% --> 60%
• cleave damage tAD scaling:  50% melee, 25% ranged  -->  40% melee, 20% ranged
  • this is a further nerf to what was already applied on 12.23

• components reordered, Stopwatch is now on the far right side, no other changes

 

Jungle:

• pet item epic monster damage reduction:  30% --> 20%
• treat gold:  35 --> 30
  • there were some changes to monster gold in the preview, but these are not minable

Mosstomper:

• shield value:  75-330 lerp --> 60-281 lerp

 

 

Changes from previous days:

General:

• Chemtech terrain was intentionally given an increased chance to spawn for preseason to give people more exposure to the new mechanics, and has now been dropped to the same chance as everything else.
• Various item tooltips claiming to be Mythic Eternity items are now fixed.

 

Champions:

Ekko:

• R tooltip now notes the W passthrough interaction

Jax:

• has rework

Udyr:

• WER mana costs:  45-28 by level --> 40-23 by level
  • reminder:  Q is still 20 mana at all levels instead
• Q:
  • tooltip now includes min damage to monsters equal to 40-160 lerp (it always had this mechanic, and was documented on the wiki, but the tooltip was missing it)
  • next two attacks target tHP scaling:
    • unempowered:  3%-10% +6%% bAD  -->  3%-8% +5%% bAD
    • empowered additional damage:  2%-5% lerp +3%% bAD  -->  2%-4% lerp +2%% bAD

Yone:

• various missing buff tooltips have been added

Zeri:

• RFC indicator updated to match her range nerfs

 

Items:

Heartsteel:

• component items reordered to have Giant's belt on the left instead of right, likely to match Warmog's order (they have identical components)

Lord Dominik's Regards:

• health difference damage amp:  up to 15% at 2000 difference --> up to 25% at 2500 difference

Radiant Virtue:

• shop search shortcut added:  "rv"

Rod of Ages:

• looks like it'll have a buff to track the haste trigger threshold?

Stormrazor:

• attack damage:  40 --> 45

 

Jungle:

• Smite damage to summoned pets updated:
  • prior to preseason, t1 Smite did the same 450 to pets, while t2 Smites did 500 +10% pet tHP
  • on live, t1 Smite deals 600 to pets, t2 Smite deals 500 +10% pet tHP (which can be less than t1's 600), and t3 deals 1200 to pets
  • on pbe, all Smites deal the same damage to pets as they do to non-pets (the percent health modified damage has been removed)

 

Runes:

Unsealed Spellbook:

• Smite damage updated:
  • prior to preseason, swapping to Smite would do 450 damage, increased to 900 if you had already made any two swaps before
  • on live, Smite will do 0 damage (yes, zero) with 0 previous swaps, and 1200 with 1+ previous swaps
  • on pbe, Smite will do 600 damage with 0 previous swaps, 900 with 1 previous swap, and 1200 with 2+ previous swaps
• These changes were available for a couple days, likely only intended to test the Smite change, and have been reverted to live:
  • first shard gained at:  6 minutes --> 30 seconds
  • initial shard cooldown:  5 minutes --> 30 seconds
  • cooldown reduction per shard:  25 seconds --> 1 second

Conditioning:

• tooltip now notes that resist amp increases bonus resists rather than total, however actual functionality seems unchanged, might have been a nerf that was tested but reverted

 

ARAM:

• Hexgate cooldown:  30s --> 15s
• Hexgate channel bar should now have a name ("Frostgate Warp", as opposed to SR's "Hexgate Warp") instead of being blank or reusing your most recent spell cast bar's name.
