Dota 2 Launches Quartero's Curios Autumn 2026 Update With Fresh Hero Sets

Valve rolled out the Quartero’s Curios event in Dota 2 on September 9, giving players a fresh batch of cosmetics to chase through the fall season. The update pairs with the kickoff of the new Dota Plus season, marking a busy week for anyone grinding levels and treasures.

The Quartero’s Curios update follows the familiar format Valve has used before: three hero sets, each unlockable at a different level threshold. This time around, Clockwerk, Treant Protector, and Windranger received new looks. Power Cogs stands out as the only ability with a full remake, while the other two heroes picked up ambient effects instead of animation overhauls.

Community reaction has already zeroed in on Treant Protector’s second style, which reimagines the hero as a burning tree. Fans on social channels have singled it out as the standout piece of the set, praising the visual concept over the more subdued Windranger and Clockwerk options.

Progression rewards kick in at level 5, where players start earning Quartero’s Antiques. Each Antique carries a chance to drop an Immortal item or an Arcana, giving grinders incentive to push through the higher levels rather than stopping once they unlock the base hero sets. According to the in-game description, the event window runs until December 4, leaving a solid three months for players to farm levels and antiques.

Dark Carnival Act 2 Still in Limbo

While Quartero’s Curios fills the current gap, the community’s attention remains fixed on Dark Carnival Act 2. The final chapters of the first act dropped before The International 2026, and Valve has stayed silent on a continuation date since then.

No official announcement has surfaced regarding when the next chapter will arrive. Players hoping for concrete news will have to keep watching for leaks, since Valve has offered no roadmap or teaser pointing to a release window.

The gap between Dark Carnival chapters isn’t unusual for Valve’s storytelling events, but it does leave players juggling side content like Quartero’s Curios to stay engaged. Whether Act 2 lands before December or slips further remains an open question.

What This Means for Players

Anyone active in the current Dota Plus season gets a built-in reason to log in daily through Quartero’s Curios. The event’s structure rewards consistent play, with the Antiques system layered on top of the standard hero set unlocks to keep the grind worthwhile past level 5.

Players focused purely on collecting the Treant Protector burning tree style or the Windranger and Clockwerk sets should plan their leveling around the December 4 cutoff. Missing that window means waiting for a potential re-release, which Valve doesn’t guarantee for every cosmetic drop.
