All sets and items from Cosmic Heroes’ Hoard 2025 with Earthshaker Arcana Planetfall in Dota 2

Valve Corporation launched a significant content update on September 16, introducing the Cosmic Heroes’ Hoard 2025 treasure chest to Dota 2. This premium cosmetic collection features seventeen complete hero sets with a particularly exciting opportunity to obtain the coveted Earthshaker Arcana, previously exclusive to Battle Pass rewards. The timing coincides with celebrating Team Falcons’ championship victory at The International 2025, creating a perfect storm of collectible content for dedicated players.

The treasure’s structure divides into two distinct categories: thirteen regularly obtainable hero sets available through standard opening, plus four special bonus items that drop alongside primary rewards. These additional drops include a Tinker Immortal item and the Earthshaker set containing the Planetfall Arcana, though trading availability remains unconfirmed at launch.

Valve simultaneously released commemorative content honoring the newly crowned TI2025 champions. Players can purchase exclusive Team Falcons champion stickers, with half the proceeds directly supporting the winning organization—continuing the tradition of champion-focused content following major tournaments.

Taurid Twilight (Spirit Breaker)

Spirit Breaker transforms into a celestial bull with this cosmic-inspired ensemble. The set features nebula-patterned armor and star-dusted horns that create particle effects during charge animations. Perfect for players who favor aggressive initiation and want their hero to visually command attention across the battlefield.

Graviton Blackguard (Enigma)

Enigma receives a gravitationally-themed makeover with black hole motifs and spacetime distortion visuals. The set significantly enhances Black Hole and Midnight Pulse animations, making these ultimate abilities even more visually spectacular during team fights.

Umbral Expanse (Void Spirit)

Void Spirit’s cosmic journey continues with this shadowy expanse design. The armor incorporates void energy patterns that pulse with otherworldly light during ability usage, creating a cohesive visual identity that matches his dimensional theme.

Frozen Nova (Ancient Apparition)

Ancient Apparition becomes a frozen celestial phenomenon with ice crystal formations and supernova-inspired effects. The set provides stunning visual upgrades to Ice Blast and Cold Feet that make his frost magic truly feel cosmically powerful.

Photax Fluttercat (Mirana)

Mirana’s majestic mount transforms into a photonic feline companion with this elegant set. Arrow animations gain star trail effects, while Leap creates brief constellation patterns at both takeoff and landing points.

Photonic Father (Zeus)

Zeus embodies pure celestial energy with lightning motifs transformed into photonic discharges. Thunderbolt and Lightning Bolt animations become miniature supernovas, perfectly fitting his godly domain over sky and storm.

Star Sage (Phoenix)

Phoenix ascends to stellar sage status with sunspot patterns and solar flare effects. Icarus Dive and Supernova abilities gain astronomical visuals that make this firebird truly feel like a cosmic entity.

Astral Schism (Sven)

Sven’s knightly armor receives an interdimensional overhaul with rift-inspired designs. Great Cleave creates spatial tear effects, while God’s Strength envelops him in astral energy that visually communicates his enhanced power state.

Narwolf Nebula (Crystal Maiden, set with persona)

Crystal Maiden’s persona set features nebula-themed robes and frost magic that appears drawn from cosmic dust rather than earthly ice. This represents one of the collection’s most comprehensive visual overhauls for players who main the iconic support hero.

Chrononaut Continuum (Faceless Void)

Faceless Void becomes a time-traveling chrononaut with continuum-themed armor and temporal distortion effects. Time Walk and Chronosphere abilities gain visual elements that emphasize his mastery over spacetime mechanics.

Cosmic Cartographer (Marci)

Marci transforms into an interstellar explorer with this beautifully designed cartographer set. The thematic consistency makes her abilities feel like tools for navigating the cosmos rather than simple combat techniques.

Reaper of the Waning Veil (Phantom Assassin, set with persona)

Phantom Assassin’s persona receives a cosmic grim reaper aesthetic with veil and waning moon motifs. Critical strike animations feature stellar explosion effects that make each killing blow feel astronomically powerful.

Flame of Origin (Lina)

Lina embodies the primordial cosmic flame with this origin-themed set. Fiery Soul stacks create miniature supernova effects, while Laguna Blade becomes a beam of pure stellar energy.

Interstellar Astrarium (Tinker, Rare)

Tinker’s rare immortal item transforms his technological arsenal into cosmic instrumentation. The Astrarium provides unique ability effects for Rearm and March of the Machines that incorporate celestial mechanics and astronomical visuals. This represents one of the collection’s most technically impressive items with layered animation sequences.

Pisces Gemini (Orge Magi, Rare)

Ogre Magi receives a zodiac-inspired rare set featuring the Pisces constellation motif. Multicast animations gain twin fish constellation effects that visually represent the dual nature of this magical brute.

Leonid Luminosity (Luna, Very Rare)

Luna’s very rare set transforms her into a celestial huntress with Leonid meteor shower-inspired effects. Lucent Beam and Eclipse abilities become meteorite barrages that create stunning visual spectacles during night-time engagements.

Intergalactic Obliterator (Earthshaker, Ultra Rare)

The crown jewel of the collection, Earthshaker’s ultra rare set includes the Planetfall Arcana with ground-breaking visual and sound effects. Each Echo Slam creates planetary impact craters with seismic waves that visually ripple across the battlefield. This represents one of Dota 2’s most visually impressive Arcanas to date.

Understanding the treasure’s probability structure is crucial for collectors seeking specific items. While Valve doesn’t publish exact drop rates, community data suggests ultra rare items like the Earthshaker Arcana typically appear in approximately 1 of every 50-75 chest openings based on historical patterns from previous treasures.

Common mistakes include opening chests impulsively without considering market alternatives. Many players waste resources chasing ultra rare drops when sometimes purchasing directly from the community market proves more cost-effective, especially for specific desired sets rather than complete collections.

Advanced optimization involves waiting 2-3 weeks post-release when market prices typically stabilize. During this period, you can assess whether buying chests or purchasing individual items represents better value based on your collection goals and budget constraints.

The Earthshaker Arcana’s trading status remains the collection’s biggest unknown factor. If it follows previous ultra rare patterns, it may become tradeable after one year, though Valve has been inconsistent with this policy recently. For immediate use, direct acquisition through chest openings remains the only guaranteed method.

For players focused on specific heroes, our Class Guide provides strategic insights that apply to cosmetic selection—matching your preferred playstyle with appropriate visual upgrades enhances both enjoyment and gameplay immersion.

Collection completionists should prioritize the regular sets first through direct opening, then evaluate market prices for the rare items. This staggered approach typically saves 20-30% compared to immediate full collection purchasing.
