Valve Corporation maintains its established pattern of distributing premium Battle Pass Arcanas through supplementary treasure systems. The current featured item is Earthshaker’s visually stunning Planetfall Arcana, originally introduced during The International 2019 championship event.
Designated as Intergalactic Obliterator, this cosmetic ensemble functions as an Ultra Rare supplementary prize within the newly launched Cosmic Heroes Hoard 2025. This classification indicates that straightforward acquisition methods remain unavailable initially, necessitating participation in randomized treasure openings. Fortunately, the container implements progressive probability scaling, meaning your likelihood of obtaining the coveted item improves with each subsequent chest you unlock.

You’ll need to open approximately 43 treasure chests to achieve the 50% cumulative probability threshold. Crucially understand that these represent aggregate probabilities across multiple attempts, not individual chance percentages per opening. This statistical distinction means you possess a 50% likelihood of having received the Ultra Rare Arcana after 43 chest openings, not a 50% probability on the 44th specific attempt.
Given the standard $3 price per chest, reaching this probability milestone demands approximately $129 in total expenditure. The treasure system incorporates a duplicate recycling mechanism that permits converting 6 unwanted item sets into an additional chest, potentially lowering net costs when pursuing specific premium rewards. However, if randomized acquisition doesn’t appeal to you, Valve typically introduces direct purchase alternatives several months post-initial release. For comprehensive trading market insights, consult our detailed analysis in the subsequent article.
Seasoned Dota 2 collectors should approach Cosmic Heroes Hoard 2025 with strategic planning. The escalating odds system creates predictable cost ceilings, but variance can significantly impact individual outcomes. Many players underestimate the distinction between cumulative probability and per-attempt chance, leading to frustration when expecting guaranteed drops at specific milestones.
Budget Optimization Tactics: Utilize the recycling feature aggressively during the first 30 chest openings, as duplicate rates remain high during initial acquisitions. Consider pooling resources with friends through gaming community coordination to maximize duplicate conversion efficiency. Track your opening history meticulously to identify when to shift from recycling to direct purchases.
Common Acquisition Pitfalls: Avoid the misconception that probability resets after each opening – the system maintains continuous progression. Don’t fall for the “sunk cost fallacy” by continuing beyond reasonable budget limits; the 65% probability mark at 50 chests often represents the optimal stopping point for cost-conscious players.
Market Timing Considerations: Historical data indicates that alternative acquisition methods typically emerge 3-6 months post-release, often through the Dota 2 store or special promotions. Patient players can frequently acquire these items at fixed prices without gambling mechanics, though this requires waiting several months.
