Razor Arcana is unlocked in The International 2022 Battle Pass. It is available for all players who reached level 383 in the Battle Pass.
The item is clearly inspired by the DotA Allstars design of the hero. He has a similar armor, helmet, shield, and a weapon. As usual, the hero gets new looks, ability effects, a complete voice change, a Static Link kills meter, and new item icons for Phase Boots, Eul's Scepter of Divinity, and Wind Waker.
There is also a second style, which can be unlocked after completing a challenge. You need to kill 500 enemies while having at least 100 damage stolen by a Static Link. You can get up to eight points per match.
This is a second Arcana in the Battle Pass for TI11. The first one belongs to Faceless Void, and is also inspired by his classic design. There is also a Crystal Maiden and Phantom Assassin personas, which completely change their characters.
