Shadow Sight

After 90 seconds two Shadow Sight powerups appear on opposite sides of the Arena. Picking one up will briefly let you see stealthed and invisible characters, at the cost of slightly damaging your health.

Prior to Patch 2.4.0, Shadow Sight would deal 2% of your total health every 5 seconds for its duration. In Patch 2.4.0, it was changed to its current settings.
