Just to mention in greater detail. Purge doesn't instantly KILL summons and Illusions. It does a specific amount of damage against them. Diffusal Blade's Purge does like buttloads of damage so it has that effect of insta-gibbing any eligible target currently in DotA. But Medusa's Gaze at lvl 1 does only 600 damage, so it wouldn't one-shot kill even a lvl 1 Infernal (which has 900 HP).
