Hi, I'm not sure exactly where this should be posted, it's not a visual glitch, more of a visual element that is missing.

In Dota 1 when you cast Illusory Orb with Puck, the projectile changes from yellow to red just before the orb disappears so the player knows that the orb is reaching max range.

In Dota 2, the Illusory Orb does not change colour in the same way.

My suggestion is of course to have this colour change implemented in Dota 2.

Thanks for your time
