Miss Fortune's Q procs the Warlord's Bloodlust mastery, even though it is not a crit.
This only happens if the first hit kills the target, granting increased damage on the second hit.
How to reproduce -
-Start a custom game
-Pick Miss Fortune
-give her the Warlord's bloodlust mastery
-Kill a minion with Double Up
