Update history and meta predictions
Numbers are transcribed from the official Riot patch notes; the commentary is ours. This page covers patch 6.3b (released 2026-05-28).
9 matches
Patch 6.3b targets ARAM and Arena and leaves the Summoner's Rift meta untouched. In ARAM, augments such as Overload and Resonating Strike are buffed heavily, which favours ability-spamming champions and marksmen. In Arena, the Anvil lets AD champions roll AP items, opening up hybrid builds.
Our take
The bonus during the mark window jumps from 30% to 50%, so setting up a mark and following through is worth going out of your way for. It does nothing without the mark, which favours champions with a reliable way to apply it. In fights it rewards committing to one target instead of spreading damage around. If the marked target simply walks away you get nothing, so having a way to follow up decides its value.
Our take
Each stack now adds half as much, so the damage no longer snowballs the way it did once stacks piled up. The gap to the old version widens with every stack, which makes building them a lower priority. Early exchanges at low stack counts change little; this is aimed squarely at the late-game total.
Our take
Five percentage points come off a max-health hit, which matters most against the tankiest targets. In ARAM everyone fights in one lane for the whole game, so percent damage shows up in nearly every exchange. Trades it used to win outright are now close, bringing it back in line with the alternatives. Saving it for a low-health target now returns more than forcing it onto the tankiest opponent.
Our take
Both lines now scale at 8% per stack, and Ability Haste in particular more than doubles. Faster ability turnaround plus extra movement speed suits champions that want to land something and reposition. Because the value compounds with stacks, there is far more reason to start collecting them early. Haste and speed climb together, which helps whether you are the one committing or the one backing out.
Our take
What used to fire once every eight seconds now effectively fires whenever the condition is met. Champions with many attacks or casts get far more triggers, which changes their total damage in a drawn-out fight. Patch 6.3c pushed this further still and removed the cooldown entirely. Roll a champion that meets the condition easily and it is worth playing forward from the first minutes.
Our take
The multiplier per basic attack doubles from 20% to 40%, so every extra swing beforehand counts twice as much. The 50–150 base is untouched, which means the payoff depends entirely on how many attacks you can land first. Paired with attack speed, the ceiling climbs quickly. Fired with no attacks beforehand, it still delivers only the unchanged base damage.
675 recorded changes across 29 versions, from 6.3 through to the current 7.3a. It is built for tracking how often a single champion has been buffed or nerfed.
The largest is 7.2 with 175 entries — the patch that rebuilt boots and introduced tier 3. Others run to a handful of lines, so the version numbers alone say nothing about how much the meta shifted.
Of the 675 entries, 231 are champion changes. The rest cover items and runes, ARAM and Arena tuning, ranked seasons and system-level work.
Selecting a version also brings up a meta prediction for that patch, 29 versions in all. It is an AI-written read rather than measured data; the tier list is where you check what the win rates actually did.
