Templar Assassin is a ranged character. Her primary attribute is agility. The hero is mainly taken as a midlaner. Most effective in the mid game.
Templar Assassin has a lot of farming potential thanks to the Refraction and Psi Blades abilities, which also allow her to deal a lot of damage in team fights and partially absorb enemy attacks. Meld allows the hero to weaken the target unit. Thanks to this ability, Templar Assassin alone is able to kill Roshan even in the early game. Psionic Trap allows her to catch up with the enemy, as well as get a small vision in places important for her and her allies. Aghanim's Shard will improve this ability making the target unit even more vulnerable. Aghanim's Scepter will allow the hero to learn Psionic Projection and become a more mobile character that can quickly move around the map.
