Dota 2 Calibration Boost

No ranked games move your MMR as much as calibration games. Win most of them and you skip weeks of climbing; lose the first few and you start a medal lower than you should. Onit.gg’s Dota 2 calibration boost hands those games to an Immortal player, either signed in to your account or queued with you, so your account starts as high as it can realistically reach.

Why the first games count most

While an account calibrates, Dota 2 tracks a Rank Confidence value next to its MMR. Confidence starts low, and while it’s low every win or loss swings your rating much harder than a normal ranked game. Your medal appears once confidence reaches 30%, so the number of games varies slightly from one account to the next. The opening games carry the most weight, which is why calibration works best when the booster plays from the very first game.

New account or recalibration

New account. Needs 100 hours played and a linked phone number first. A strong run has the widest effect here, so it’s best for starting ranked in the right bracket from day one.

Recalibration. Available once a year from the Account section of the in-game settings. You land near your previous rank — a good run adds MMR but won’t jump you several medals. If you want a much higher medal afterwards, add an MMR climb from your new starting point.

What’s in the order

• Your calibration matches played by hand by one of our own Immortal boosters
• Core, support or any role, whichever your account normally plays
• Games on your own server region, with offline status throughout
• Chat with your booster on our website
• The MMR and medal the games earn, kept on your account

Timing

With priority on, your order starts within 90 minutes; standard orders start within 24 hours. A full set of calibration games usually takes 12 to 24 hours of play. Because the order is short, the booster plays straight through and hands the account back when the medal appears.

Account sharing is against Valve’s rules, so a boost played on your account always carries some risk. We keep it low with a VPN set to your country, offline status, and no scripts or third-party software. Party play below 8,500 MMR involves no account sharing.
