October 12, 2026
Valve officially released the latest Arcana for Tidehunter in Dota 2 through an update titled Inside the Trove of Terror on October 7, 2026. Named Maw of the Megalodon, this Arcana features a new design that transforms Tidehunter into a massive shark-like sea monster. Its arrival is one of the main highlights of the horror-themed cosmetic update released ahead of Halloween.
This Arcana also marks the first time Tidehunter has received a cosmetic item with Arcana rarity. Valve has introduced various visual changes that make the hero look more intimidating when entering the battlefield.
Maw of the Megalodon Features a New Model and Effects
With Maw of the Megalodon, Tidehunter receives a new character model inspired by the Megalodon, an enormous prehistoric shark species. The design emphasizes the characteristics of a marine predator, giving him a fiercer and more terrifying appearance than his standard model.
Valve has also equipped this Arcana with various exclusive features, including custom animations, visual effects, a taunt, and new voice lines. In addition, Tidehunter appears to carry a corpse-like figure as part of his cosmetic design, adding a dark yet distinctive touch to his appearance.
Interestingly, Maw of the Megalodon features three shark-themed design variations that players can unlock. This feature provides additional customization options for players who want to tailor Tidehunter’s appearance to their preferences.
With all these changes, the Arcana is more than just a character model replacement. It gives Tidehunter a completely new visual identity in Dota 2.
Trove of Terror Introduces More Cosmetic Items

In addition to Tidehunter’s Arcana, the Inside the Trove of Terror update introduces 15 new Immortal item sets featuring horror-inspired designs and creatures from otherworldly realms. The update also brings back Drow Ranger’s previously released Arcana, this time with an additional appearance.
Valve has also introduced new appearances for Tormentor and Roshan associated with the unlocking of certain treasures. As a result, Trove of Terror offers a variety of cosmetics that may appeal to both item collectors and Dota 2 players.
Players can access the update through the Dota 2 client to check the treasure contents and the requirements for available rewards. Before opening any treasures, players should review the costs and reward mechanics listed in the game.
Maw of the Megalodon is the main highlight of this update, particularly for Tidehunter players and Arcana collectors. With its shark-monster design, custom animations, and three appearance variations, Valve brings a fresh look to one of Dota 2’s iconic offlane heroes.
