How to counter Templar Assassin in Dota 2

Templar Assassin becomes highly elusive, gaining a small barrier and bonus to her damage. The damage and avoidance effects are separate, and have a limited number of instances. If a barrier is consumed, a new one is created as long as there are charges left. If an instance of damage would deal more damage than the remaining barrier, all of the damage is absorbed.

Templar Assassin conceals herself, becoming invisible as long as she remains still. If Meld's invisibility is broken by attacking an enemy, Lanaya's attack will deal bonus damage to the enemy and reduce their armor for 6 seconds. Bonus damage and armor reductions are applied to all enemies in the Psi Blades split range.

Templar Assassin's psi blades slice through the attacked unit, splitting and damaging enemy units directly behind it, while gaining bonus attack range. For each unit it damages, the split damage is reduced by a percentage.
