It should be something like the quest notification that you get on Twisted Treeline, Dominion, and in-game champ interactions(Kha'Zix vs. Rengar, AshexSejuanixLissandra), you know the ones at the right edge of the screen? But it should have more sound effects like and slightly bigger so that it would achieve the impact it should bring.

Or when it appears it should quickly move to the right or left edge of the screen(most preferably the right side) while shrinking into acceptable size.

Ooooooooooooor something like that.

P.S.: Legendary kill should get more... stuff I dunno how to call it, so that it feels more prestigious since it is hard and pretty conditional to pull off.
