This papercraft is Lanaya the Templar Assassin, a short-ranged Agility hero capable of dealing huge bursts of Physical damage to swathes of enemies with expert positioning and timing, based on the DotA 2 multiplayer online battle video game, the paper model was created by Ardian Tjeng, shared by Kang Papercraft.
Unlike most physical damage dealers, Lanaya reaches her damage potential quite early and then scales up from that point with carry items, letting her gank with impunity throughout the mid-game, and her range changes from a melee hero to a ranged hero with short reach as she levels Psi Blades.
Her Psionic Traps provide map control and the ability to chase down fleeing heroes from up to 2000 range, and Refraction and Meld lets you shrug off high-damage nukes and disjoint projectiles. With a Blink Dagger, Lanaya can quickly materialize in the enemy team's weakest flank and shred several heroes at once with her Meld and Psi Blades. [Source: GamePedia]
