ARAM Mayhem Overlay
A Mayhem helper that sits next to your League client: the strongest champion on your bench in the lobby, the tier of every card you're offered for your champion, and your build in the overlay. Native for Windows, without ads or Overwolf.
Free: each champion's Mayhem tier and its top 5 cards. Plus (€4.99 a month or €39 a year) adds every card, the color filter, the builds and the card picker, with 7 days free to try.
What it shows in a Mayhem game
In the lobby: the best champion you can get
LazyElo scores your own champion, your champion choices and every champion on the bench: its Mayhem tier and win rate, your mastery and your own Mayhem record on it, and how it fits your team. When a swap is clearly better it says which one and why. You do the swapping.
Each augment pick: the three cards side by side
Type the three cards you're offered (a few letters is enough) and LazyElo shows what each one does and its tier for your champion, next to each other. You type the cards yourself: the app doesn't read your screen.
Your champion's card tiers and build
For the champion you end up on: every card by tier for the 1st, 2nd, 3rd or 4th pick, a filter per rarity, the strongest card pairs, and the build with items in buying order, summoner spells and skill order.
In game: the overlay
The overlay shows your Mayhem build in the game, next to the scoreboard view of both teams: level, K/D/A, items and who is ahead.
The overlay in game
Where the Mayhem numbers come from
- Riot keeps Mayhem games out of its public match API. The champion tiers, card tiers and builds come from ARAMKit, used with permission, and are the same as on this site's Mayhem tier list, augment tier list and build pages.
- Your own record comes from the Mayhem games in your League client's history, read on your own PC.
- Cards are shown by tier and order only, never with a win rate, as Riot's policy asks.
Light on your PC
What LazyElo asks of your PC: first what follows from how it is built, then what we measured. We only put a number here once we have measured it.
By design
Native, without Overwolf
A Windows app of its own. No Overwolf and no browser engine running next to your game.
No ads
Nothing in the app loads ads or ad videos, in the lobby or during a game.
A small overlay
The overlay is a separate see-through window. It only draws scoreboard info and redraws twice a second.
Nothing inside the game
LazyElo reads the client and the game's own live data through the local connections Riot provides. It never runs inside the game process and never reads game memory.

Our own measurements, on one PC. RAM is the working set Windows reports for LazyElo. The numbers during a game and an FPS test with and without LazyElo follow here; until then we make no claim about them.
