Riot was trying to remove the randomness on the game, they removed dodge chance and gave critical strike a pseudoRNG system to make it more consistent. But critical strike chance is still there and I thing it could be changed to a more consistent system.

They also created bonus Armor penetration (on YasuoSquare Yasuo's Last Breath Last Breath and CaitlynSquare Caitlyn's Headshot Headshot) and reworked The Black Cleaver item The Black Cleaver because it was a good item against both squishy and tanky enemies.

So these are my proposals:

Critical Damage

Critical strike icon Critical strike no longer grants a probability to deal increased damage from autoattacks, instead it constantly increases damage autoattacks deal, up to 100% bonus damage dealt.

Critical Damage Runes

Critical Chance runes converted into Critical Damage runes. If you have more than 9 Critical Damage runes of the same type after the conversion (or 3 Quintaessences), extra runes are removed and you get 410IP icon Influence Points for every rune removed (1205IP icon Influence Points for Quintaessences).

Critical Damage runes now cost 410IP icon Influence Points (1205IP icon Influence Points for Quintaessences) and they now increase critical damage by 0,93% per Mark, 0,42% per Seal, 0,28% per Glyph or 1,86% for Quintaessence.

Critical Damage Items

All items that formerly gave Critical Strike Chance now give the same quantity of Critical Damage.

Infinity Edge item Infinity Edge is reworked. This rework will be explained on the Armor Penetration section.

Abilities that interact with Critical Damage

These abilities formely modified Critical Strike chance or damage:

  • PantheonSquare Pantheon's Certain Death Certain Death grants him 100% critical damage against targets below 15% of their maximum health and makes PantheonSquare Pantheon's Spear Shot Spear Shot benefit from critical damage against targets below the same threshold.
  • ShacoSquare Shaco's Deceive Deceive grants him 40 / 60 / 80 / 100 / 120% critical damage on his next attack, but for modified critical damage.
  • TryndamereSquare Tryndamere's Battle Fury Battle Fury passively increases his critical damage by 0.35% per point of Fury he currently has.
  • YasuoSquare Yasuo's Way of the Wanderer Way of the Wanderer increases his critical damage by an extra 0,8% for every 1% he gets.
  • AsheSquare Ashe's Frost Shot Frost Shot makes her deal 10% AD bonus damage to frozen targets. It no longer modifies critical damage.

The way these abilities are affected by critical damage is modified:

Armor and Magic Penetration

Flat armor penetration and flat magic penetration unchanged. This kind of penetration is intended to be strong against targets with low resistances, so it's OK as it works now.

Percentage armor penetration and percentaje magic penetration are supposed to be used against high resistances targets, but they're actually strong against low resistances targets too, so it now only applies to bonus Armor or Magic Resist.

I also want Infinity Edge item Infinity Edge to be still an interesting item, so it's now an Armor Penetration alternative to Last Whisper item Last Whisper.

Last Whisper item Last Whisper

  • Passive changed from "+35% armor penetration" to "Armor Penetration: +50% bonus armor penetration"

Void Staff item Void Staff

  • Passive changed from "+35% magic penetration" to "+50% bonus magic resist penetration"

Infinity Edge item Infinity Edge

  • Current passive removed.
  • New passive: "Armor Penetration: +50% bonus armor penetration on basic attacks".

Whith these changes Last Whisper item Last Whisper is now an item suited for AD Casters as the armor penetration it gives applies to all your damage, while Infinity Edge item Infinity Edge is still designed for autoattackers, as it's passive only applies to basic attacks.

As both items have the same passive name, they can't be stacked.

Other changes:

  • Devastating Strikes mastery 2014.png Devastating Strikes now grants 4 / 7 / 10% bonus armor penetration and bonus magic resist penetration.
  • DariusSquare Darius' Apprehend Apprehend now passively grants him 7 / 14 / 21 / 28 / 35% bonus armor penetration.

Liandry's Torment item Liandry's Torment

Liandry's Torment is, as old Black Cleaver, an item that is oriented to give damage against tanky targets, while also giving damage against squishy ones, so I want to divide this item in 2:

  • The new Liandry's Torment, which will keep his health % damage,
  • And a new one, that will be the late game upgrade to Haunting Guise item Haunting Guise.

Liandry's Torment item Liandry's Torment

  • New Recipe: Aether Wisp item Aether Wisp + Blasting Wand item Blasting Wand +Giant's Belt item Giant's Belt + 590Gold Gold = 3300Gold Gold
  • Ability Power increased to 80 from 50.
  • Health increased to 400 from 300.
  • Magic Penetration removed.
  • It now grants +6% movement speed.
  • Passive unchanged.

Deathfire Grasp item Deathfire Grasp

  • It returns to the game, but totally changed.
  • Recipe: Haunting Guise item Haunting Guise + Blasting Wand item Blasting Wand + 355Gold Gold = 2700Gold Gold
  • Stats: +80 ability power, +250 health
  • Unique Passive - Eyes of pain:: +25 Magic Penetration
