Mercury's Treads as boots
It does clearly better than Ionian Boots of Lucidity in the 10 minutes after buying. It loses that edge later in the game.
Mains view. This shows what players who main Kha'Zix (it’s their #1 mastery champion) pick in 570 of their games. The verdicts and numbers are still everyone’s. Mains get their own at 1,500 games. Everyone’s page
Not enough games after this pair yet. Pick a more common second item, or see every option below.
This is every step as Kha'Zix mains play it. Their most picked option comes first.
The main number is how much more an option wins than the most picked one in similar games. Those are games with the same game state and minute of purchase, played on the same patch by players with as much experience. A +2.0% means about two more wins per 100 games. Numbers from few games are pulled toward what the option does on other champions.
± is the marginMargin (±)The real number is very likely inside this range. More games make it narrower.. The real difference is very likely inside it. On the bar, the dot is the number and the band is the margin. The black line means no difference.
Better or Worse means the whole margin is on one side of zero and the difference is at least half a point. Even means we know the two are within a point of each other. Unclear means it could go either way. With Not enough games, there are too few games to say anything yet.
vs expected (WPA) asks whether games with the option ended better than their win chance when it was chosen. It doesn’t compare options with each other. Next to it is the win chance it’s usually taken at.

It does clearly better than Ionian Boots of Lucidity in the 10 minutes after buying. It loses that edge later in the game.
Items when behind or ahead
Each item is compared with the slot’s most bought one over the 10 minutes after it’s bought. Games are split by whether Kha'Zix was behind (40% win chance or less when bought), even, or ahead (60% or more). Where Kha'Zix’s own purchases are few, the number leans on every jungle that buys the item.
No item does clearly better or worse than the most bought one in any game state yet. Stick with the usual build.

Everyone or mains
Mains are players whose #1 mastery champion is this one. We know the mastery of 717,000 ranked players from Platinum to Challenger. That covers about half the players in our games. Below 1,500 games by mains, the mains view shows what they pick next to everyone’s verdicts. From 1,500 games on, every number is the mains’ own.
WPA (win probability added)
On the pages it’s labelled “vs expected”. It compares how games with the option ended with the win chance they had when it was chosen (the draft for runes and spells, the minute of purchase for items). +1.0% is about one more win per 100 games than expected. The comparison is with what players usually do from there. It can’t compare two options with each other. Because popular options make up most of what “usual” is, it understates them. Options that strong players favor also look better here than they are. Use it as a hint and let the main number decide the verdict.
Win chance against the most picked
This is how much more each option wins than the most picked one, in points of win chance. The games compared have the same draft odds or game state, the same patch and the same player experience. Numbers from few games are then pulled toward what the same option does on other champions. A number from 300 games keeps little of its size. With thousands of games, most of it stays.
Better, worse, even, unclear
The verdict reads the number after the pull and its 95% margin (±). Better or Worse needs the whole margin on one side of zero and a difference of at least half a point. Even means we know the two are within a point of each other. When it could go either way, the verdict is Unclear. Not enough games means too few players tried both, or the number is mostly the pull.
Lane, mid and late game
The difference is split by when the win chance moved: lane (0–14 min), mid game (14–25) and late game (25 to the end). The three add up to the whole game. They show when an option pays off or costs you.
After the purchase
An item counts only from the minute it’s finished. Its numbers cover the 10 minutes after the purchase and the rest of the game. What happened before the purchase explains why the item was bought. Those minutes don’t count toward the item.
Not enough games
There are too few games to say anything yet. The margin would be wider than ±5%, or the number would be too noisy to say anything. The number appears once more games narrow the margin.
What the data says
We run seven checks on every champion. Two flag common picks that cost win chance and results carried by one player. The others catch theory that real games don’t back, answers that change with your build, keystone gaps that go with the build, options that pay off in only one phase, and lanes that turn after minute 14.
Pays off in one phase
This option’s whole-game number hides what happens in one phase. For example, it may win lane and lose that edge later, or pay off late. The number for that phase moves at least 1%.
