Following the same path as Rubick, Valve has released an Arcana item for Earthshaker called Planetfall that can be unlocked at The International 2019 Battle Pass level 365.
Similar to the previous Arcana item release, Planetfall Earthshaker Arcana also includes fancy in-game features. These are the all-new model and custom effects for Echo Slam, Enchant Totem, Blink Dagger, and stun effects. Planet Arcana also features an exclusive Earthshaker voice and players will also unlock more Arcana styles once a certain requirement is met.
As mentioned above, Planetfall Earthshaker Arcana can be unlocked at level 365 of TI9 Battle Pass. There are three options for players who want to purchase the Battle Pass. The standard Battle Pass which will only unlock 1 level for $9.99, unlock 50 levels for $29.35, and unlock 100 levels for $44.99.
Obviously, players can slowly unlock more level after they complete a mission. However, completing all the missions will not get you to level 365. In short, you still need to spend more if you’re planning to unlock Earthshaker Arcana.
