Roshan the Immortal has smashed his way into a labyrinth beneath his lair, driven to frenzy by the scent of the world's rarest cheese. In today's update, all Battle Pass owners are invited to follow his path and descend into the Underhollow, where a proving ground of teamwork and battle tactics awaits—along with a supply of Battle Points for those bold enough to seize them.

Party up with two friends or queue-met allies to navigate your way through this maze of monstrous hordes and vile traps. Work together to outwit and outlast the seven other teams each fighting to be the last group standing.

Each week you'll have new chances to earn Battle Points by winning a clash outright as the last team standing, killing any opponents during battle, or unearthing rare and valuable cheeses—such as the coveted Roshefort wheel. But remember: Roshan is on his own quest, and his frenzy is causing the Underhollow to collapse around him. You'll need to step quickly and choose your path wisely to have any hopes of escaping alive.

In the first 30 hours since recalibration, the matchmaker was overly sensitive on wins and losses and it resulted in players calibrating with bigger gains and losses than intended. We are processing all matches again and will be correcting the rank gains and losses throughout the day. Medals will be appear as undefined for a bit during this process.

- Zeus’s Nimbus particle effect now always shows properly if you can see parts of the affected area, rather than needing to see the center of it.

The new Ranked Season of Dota will go live with tomorrow’s update. As we kick off the season, your new Ranked Medal will be calculated through a calibration period of ten games. This season's calibration will allow for a substantial change in rank based on your performance during calibration, seeded by your previous rank. Your previous season’s medal will be displayed in your profile, alongside your new medal.

We've made some changes to the Ranked Medal system itself. You'll now be able to see the progress on your profile medal, visible only to you, to track your advancement towards the next star or rank. Additionally, the steps between ranks go from 1 star to 5 stars, instead of 0 to 5. There is also a new tier of Ranked Medal exclusively for players positioned on the Leaderboards — designated as Immortal — to help more clearly distinguish the top players in the world. The Immortal rank does not have stars, just the explicit leaderboard ranking.

As always, Rank Medals represent your highest performance level for the current season, and a medal will never decrease in rank once you've earned it. Once you've calibrated your new ranking, there's nowhere to go but up.

* Using Control + Alt in Quick Buy area now tells you how much gold you need for both the item and buyback

- Added Beta support for Vulkan on macOS (requires installing Vulkan DLC). Vulkan for macOS DLC provides improved performance and reduced stutters on macOS 10.13+ with a Metal-capable GPU. Vulkan support on macOS still in beta, please file any issues at https://github.com/ValveSoftware/Dota-2-Vulkan

The International 2018 Collector’s Cache has arrived. Available exclusively to Battle Pass owners for $1.99, and brimming with 14 subterranean-themed item sets—and three rare sets—the Collector's Cache is ready to unearth a rich seam of heroes suitably styled for this year’s event.

Unboxing fourteen of these treasures automatically grants you 27 Battle Levels. As always, the chances for a rare drop increase with each treasure you open, and each purchase contributes directly to The International prize pool.

As in years past, this treasure is only available for sale until The International concludes, and the items inside are exclusive and cannot be purchased elsewhere. Each set can, however, be gifted once or recycled for 2,000 Battle Points, and the Ultra Rare is marketable.
