Valve released a new update for Dota 2 on March 11, 2026, featuring the spring Quartero’s Curious event. This update adds three new cosmetic sets and spring-themed item effects. Players can earn rewards by leveling up during the event, which runs until June 4.
The Dota 2 update on March 11, 2026, launched the spring Quartero’s Curious event, bringing fresh cosmetic content to the game. Three new sets were added: Death Prophet – The Blue Lotus, Mars with two styles – The Red Berserker and WorldsEnd, and Zeus – Stormfather. These sets draw references to ancient mythological creatures and are assembled from separate items obtained through leveling up.
Antiques play a key role, particularly at level 5, where players can acquire rare in-game items such as Immortal or Arcana pieces. A notable change prevents duplicate rewards when opening Antiques. Upon completing the event, subsequent levels earned will provide Dota Plus points. The update also introduces Quartero’s sister alongside the main character.
From levels 2 to 29, players unlock 10 new in-game item effects styled for spring. These additions aim to refresh the visual elements of Dota 2. The event concludes on June 4, giving participants time to collect the primary rewards, including sets and Antiques.
This update focuses on cosmetic enhancements and rewards, maintaining the game's tradition of seasonal events.
