It is strong if you manage to hit a single target with it, but with just 2 targets it becomes 180+0.3AP which has less scaling than Ahri's trua damage, and Ahri's ability got same ammount of damage in magic form, easier to land and does the same amount of damage regardless of number of targets.

Darius got massive 1.5AD scaling with potential refresh, and Invoker got no ult ability, so most of his abilities are mini-ult-like with big CDs.

I think it has more potention to be used as counter jungling tool with help or wards or cv.
