Your Mythic+ rating — commonly called your M+ score or IO score — is the number that defines your reputation in WoW's dungeon endgame. Groups use it to invite you, it reflects how hard you push, and hitting score milestones earns achievements and rewards. This guide explains exactly how the score is calculated and how a Mythic+ score boost works.

What is Mythic+ rating?

Mythic+ rating is a season-long score that measures your dungeon performance across the entire pool of Mythic+ dungeons. Every dungeon has two timers you can score on, and your rating is the sum of your best runs in each dungeon. The higher the key level you complete — and the better your timer — the more rating that run contributes. In-game the rating is shown by Blizzard directly, and community sites like Raider.IO track it, which is where the nickname "IO score" comes from.

How the score is built

  • Per-dungeon scoring: Each dungeon in the seasonal pool contributes a score based on your best completion there.
  • Key level and timer: Higher keys award more points, and beating the timer awards more than an over-time completion.
  • Both affixes/routes: You are rewarded for having strong runs across the whole dungeon pool, not just one dungeon, so a balanced set of high keys maximizes your total.

Why score milestones matter

Score is not just bragging rights — it gates real things:

  • Group invites: Higher-key groups filter applicants by score, so a low rating can lock you out of the pushing scene even if you are capable.
  • Seasonal achievements and rewards: Reaching score thresholds unlocks achievements, and pushing high keys feeds better Great Vault rewards.
  • Portals and titles: Timing high-enough keys in every dungeon unlocks the season's dungeon teleports, a permanent quality-of-life reward.

The chicken-and-egg problem

Mythic+ has a well-known catch: to get invited to high keys you need a high score, but to get a high score you need to complete high keys. Pugging up the ladder is slow and frustrating when groups pass over you for someone with a slightly higher number, and a few bricked keys (missed timers) can stall your progress for a whole week. This is exactly where a boost helps break the loop.

How a Mythic+ score boost works

A Mythic+ boost puts you in a group of experienced players who reliably time keys at a target level. Two common formats:

  • Self-play: You play your own character in a group of skilled boosters who handle routing, kicks, and mechanics, timing keys to raise your score while you keep control.
  • Piloted: An experienced player plays your character to hit the target score or timed-key milestone.

The deliverable is a specific outcome — a target M+ rating, a set of timed keys for the teleport achievement, or a filled Mythic+ Great Vault slot for the week.

What affects the price

  • Target key level or score: Higher keys are exponentially harder to time, so pushing a high score costs more than a modest one.
  • Timed vs completed: Guaranteed-timed runs cost more than simple completions.
  • Self-play vs piloted and whether you need a full dungeon sweep for teleports.

Our WoW Mythic+ boosting covers single key completions, full timed sweeps for the seasonal teleports, score pushes to a target rating, and weekly Great Vault fills, with self-play and piloted options.

Is a Mythic+ score boost worth it?

If you are stuck below the score groups want, a boost can break the invite deadlock and get you into the pushing bracket where you can hold your own. If you want the dungeon teleports before the season ends, a timed sweep is a reliable way to secure them. If your goal is to genuinely improve at higher keys, choose the self-play format so you learn the routes and mechanics alongside strong players. As always, a boost is a head start — keep pushing keys yourself to maintain and grow your rating.

The bottom line

Your Mythic+ rating is the sum of your best timed runs across the dungeon pool, and it gates group invites, achievements, teleports, and Vault rewards. The invite-versus-score catch-22 makes it hard to climb solo. A Mythic+ score boost — self-play to learn or piloted for speed — is a legitimate way to reach a target rating, unlock the seasonal teleports, or keep your Vault full, priced by how high you want to push.
