The Anti-Mage persona became available for all The International 10 Battle Pass owners who raised their pass to level 305. It unlocks a female model, who according to the lore released along with the item, is Anti-Mage’s disciple.
Her name is Wei and comes with a new set of animations, over 900 exclusive voice lines, an all-new hero portrait and minimap icon, but unlike all the arcana, immortal and previous persona items, it comes with absolutely no ambient/particle effects.
Wei is at the beginning of her own journey in discovering the world of magic, according to the lore and perhaps that’s the biggest reason for which the item set has no explosion of particles.
The International 10 Battle Pass contains two persona and three arcana item sets. Wei, the Anti-Mage persona is the first released by Valve. The second one is still pending and it’s a Toy Butcher cosmetic for Pudge that unlocks at level 255. Besides the Anti-Mage persona, the TI 10 Battle Pass owners can also unlock the Queen of Pain arcana, Eminence of Ristul, which is available at level 455, and the One True King arcana for Wraith King, available at level 375.
Both Arcana sets have an evolving feature which allows the players to grind towards a second style that changes the basic colors of the sets. The third Arcana of the TI10 Battle Pass is for Windranger. Titled Compass of the Rising Gale, it will become available at level 575, once Valve releases the cosmetic.
