Selected changes, not a win-rate ranking
Key point: These dated examples require checking today’s client version and latest notes.

This article explains the August 25, 2026 patch notes as a dated example. It is not a claim that 26.17 is the current live patch or a current champion tier list. Check your client’s version and Riot’s latest notes before applying the numbers to a match today.

Three concrete changes

ChampionSelected official change
Aurelion SolQ mana cost per second reduced by 5 at each rank; W cooldown at rank 5 changes from 16 to 14 seconds.
GravesQ initial bonus-AD ratio: 65% → 55%.
IreliaQ AD ratio: 70% → 80%.
Key point: The table covers selected changes rather than the entire patch.

This is a selected set from Riot’s 26.17 notes, not a full patch reproduction.

Work out the changed component, not an imaginary win rate

Key point: Graves’ coefficient reduction changes one damage component, not every attack by ten percent.

Graves is the clearest example of a percentage-point trap. His Q initial-hit coefficient changed from 65% to 55% bonus AD. With an illustrative 100 bonus AD, that component contributes 65 damage before the change and 55 afterward: 10 less raw damage. It does not mean every Graves attack, or even the entire Q, deals ten percent less damage.

Key point: At 100 bonus AD, both changed coefficients together remove 20 raw damage if both hits land.

The same notes also reduce the Q return-hit bonus-AD coefficient by ten percentage points at each rank. If both hits land and the hypothetical build has 100 bonus AD, the combined change from those two coefficients is 20 raw damage before defenses and other modifiers. Separating the two hits matters because a target may not take both.

Illustrative calculationWhat it demonstrates
Irelia Q at 200 total AD: 0.70 × 200 = 140; 0.80 × 200 = 160The AD component gains 20 raw damage. This is not total final damage.
Aurelion Sol Q: a 5-mana reduction per second across an illustrative 3 seconds = 15 manaA smaller resource cost can change how long a pattern is sustainable; this is not a full spell-cost simulation.
Aurelion Sol W: rank 1 remains 22s; rank 5 changes 16s to 14sThe two-second maximum-rank improvement should not be described as a two-second buff at every rank.
Key point: Keep the calculation’s inputs and match context beside the headline number.

Keep base damage, the relevant AD measure, ability rank, defenses and mode beside the calculation. The numbers give you a practice question, not permission to declare a champion unbeatable. A build, matchup or timing change can matter more to one player than the single coefficient they noticed in a headline.

Separate the modes in a long patch note

Key point: Check each section’s mode before applying an adjustment to your match.

The same official document includes sections for other modes, including Classic and Arena. A familiar champion name appearing further down does not mean every listed adjustment applies to the mode you queue for. Read the surrounding heading before saving an item recommendation or copying a build.

Try one deliberate change

Key point: Test one relevant question without changing the entire build or inventing win rates.

For your next session, choose one question related to your own champion: whether a resource limit changes how you trade, or whether a familiar damage expectation now needs adjustment. Compare the same kind of situation and avoid changing your entire build at once. The patch gives values; it does not supply a verified win-rate ranking, and this article does not invent one.
