Dota 2 MMR Boosting Guide: Medals, Valve's Rules and Risks

Dota 2 MMR boosting breaks the Steam Subscriber Agreement when a booster logs into your account: your Steam account is personal, and you may not share your password, sell it, charge others for using it or transfer it. Valve has banned Dota 2 account buyers and sellers in ban waves, blacklisted the phone numbers of banned accounts from ranked, and gone after main accounts linked to smurfs. Party boosting keeps your login private, but a booster's smurf can drag your account into the same scrutiny. This guide covers medals and MMR, ranked requirements, what Valve enforces, behavior score, party boosts, prices and how to choose a site.

Checked against the Steam Subscriber Agreement and the Dota 2 Steam store page, with Valve's ranked and ban changes as reported by GosuGamers, PC Gamer, Dexerto and Wikipedia on November 12, 2026.

How do Dota 2 medals and MMR work?

Dota 2 shows your skill as a medal: Herald, Guardian, Crusader, Archon, Legend, Ancient, Divine and Immortal. Each medal below Immortal has five stars, and behind the medal sits your MMR, which rises when you win and falls when you lose.

MedalStarsNotes
Herald1 to 5Lowest medal
Guardian1 to 5
Crusader1 to 5
Archon1 to 5
Legend1 to 5
Ancient1 to 5Prices usually climb steeply from here
Divine1 to 5Highest medal with stars
ImmortalNoneShows a regional leaderboard position instead

Immortal players are listed on Valve's regional leaderboards, so an order into Immortal is really an order for a leaderboard placement. Because medals map to MMR, boosts are usually priced per MMR or per star, and quotes rise steeply once you pass Ancient.

If the difference between your hidden rating and your visible rank is new to you, our MMR vs rank explainer covers it. In Dota 2 the medal is a direct readout of MMR bands, which is why sellers ask for your exact MMR before quoting.

What do you need to play ranked Dota 2?

You need a unique phone number linked to your account and enough unranked playtime before ranked opens up. Valve made phone numbers mandatory for ranked in 2017 and later added a 100-hour playtime requirement, then calibration games to place you.

RequirementDetailWhy it matters for boosting
Unique phone numberRequired for ranked since 2017, aimed at griefing and smurfingEach ranked account traces back to a real number
100 hours playedValve added it as an anti-smurf ruleFresh accounts can't jump into ranked
Calibration gamesTen games to set your first medal, per DexertoCalibration boosts are a product in their own right
Phone number blacklistNumbers from banned accounts are blocked from rankedA ban can follow your number to a new account

That last row is easy to miss. When Valve bans an account for account trading or behavior, the phone number tied to it can't be used for ranked again. A ban from a boost can lock you out of ranked on any new account that uses the same number.

Is Dota 2 MMR boosting bannable?

Yes, if the boost involves your login or an account sale. The Steam Subscriber Agreement makes your account personal and bans sharing your password or charging others to use it, and Valve has run Dota 2 ban waves aimed at account buyers and sellers.

Valve's own update admitted that its account-sale detection doesn't catch every sale but said it catches enough to act. That's an honest picture of enforcement: not certain, not rare. Is Boosting Bannable? compares Valve's approach with Riot's and Blizzard's.

Can a booster hurt your Dota 2 behavior score?

Yes. Reports, abandons and toxic chat on your account lower your standing, and players who are reported often or abandon games end up in low priority matchmaking.

Behavior score sits alongside MMR, and it outlasts the boost. Valve has banned players with very low behavior scores in the same waves that targeted account sellers, so a booster who flames, abandons or griefs while on your account can leave you worse off than before.

  • Abandons. Leaving a game, even to restart a bad one, counts against your account and can send it to low priority.
  • Chat. Ask for an order with all chat off. A booster gains nothing from talking.
  • Role abuse. Valve added reports for role abuse during the draft, so a booster who ignores the role your party picked can draw reports.
  • Exploits. Valve said players who repeatedly use exploits will be banned, so bug abuse to speed up wins isn't a shortcut.

Before an order starts, screenshot your profile, medal and recent matches. If reports or low priority show up during the order, you have evidence for a refund claim.

Is party boosting safer than account sharing in Dota 2?

Safer for your login, yes. You play your own games with the booster in your party, so nothing touches your password; the remaining risk sits on the booster's account.

Dota 2 supports ranked parties, so a booster can queue with you instead of logging in. Most high-MMR boosters play from a smurf for this, and Valve's smurf crackdowns traced those accounts to their owners' mains. Your account isn't the smurf, but you're in its match history, and you depend on the booster's account surviving the order.

Password sharedNoYes, against the Steam Subscriber Agreement

SpeedSlower; you play every gameFaster
Main riskThe booster's smurf being banned mid-orderAccount penalties and your Steam login

Check with the seller that your MMR and the booster's can queue together in ranked before you pay, and ask what happens if the booster's account is banned halfway through. A refund for the unplayed part should be in writing.

What happens if a booster cheats on your Dota 2 account?

You can lose the account for good. Dota 2's Steam page lists Valve Anti-Cheat, and VAC bans are permanent, non-negotiable and shown publicly on your Steam profile.

A VAC ban is tied to your Steam account, not to the booster. It stays on your profile for anyone to see, and Valve doesn't negotiate it away. Under the Steam Subscriber Agreement, helping a third party use cheats is itself a breach, so letting a booster run scripts on your account is the worst kind of boost you can buy.

Any seller who mentions scripts, tools or guaranteed win rates is telling you how the order will be done. Walk away; 12 Red Flags of a Boosting Scam lists the other signs.

How much does Dota 2 MMR boosting cost?

Most sites price per block of MMR or per medal star, and the cost per point climbs steeply from Ancient into Divine and Immortal. Party boosts, calibration games and behavior-related orders are priced separately.

Order typeUsually priced byWatch out for
MMR boostPer block of MMRQuotes based on a medal instead of your exact MMR
Party boostPer game or per MMRSlower pace; the booster's smurf can be banned mid-order
Calibration gamesPer gamePromises of a specific medal from calibration
Low priority gamesPer gameNeeds account sharing on an account that's already flagged for behavior
Immortal or leaderboard pushCustom quoteA leaderboard position keeps moving after delivery

Low priority orders deserve a second look. An account in low priority is already marked for reports or abandons, and handing it to a stranger adds account sharing on top. For the price drivers that apply across games, read How Much Does Boosting Cost?.

How do you choose a Dota 2 boosting site?

Choose a site that protects your behavior score, offers party boosts, prices by your exact MMR, and puts refund terms in writing. Then compare final prices with every add-on included.

  1. Give the seller your exact MMR and ask for a per-MMR price, not just a medal target.
  2. Ask how the site protects your behavior score: no abandons, no chat, no role abuse.
  3. Prefer party boosts; for account sharing, ask for a booster in your region and no exploit use.
  4. Check the refund policy covers unfinished orders and account penalties.
  5. Compare sites in our best Dota 2 boosting services ranking.
