Hextech Rocketbelt

Unique – Supersonic: Dash 275 units in the target direction, though not through terrain, then unleash an arc of 7 rockets forward which upon collision explode in a 185-radius area. Enemies within 85 units of your dash, a 400 unit distance behind you^(note), and ones hit by any rocket's explosion are dealt 100 (+ 10% AP) magic damage, once per cast (40 second cooldown; 1050 rocket range).
Supersonic resets the user's basic attack timer.
