Artful Takedown

"Dimir assassinations are choreographed like dance routines. Each challenge is anticipated and countered with graceful ease." - Diary of a Dead Rogue

As a reaction to an enemy moving more than 5ft, you artfully maneuver for the takedown with everything proceeding as planned.

When an enemy that you can see moves more than 5 ft, you may use your reaction to shift through the shadows and appear behind that enemy, making a single melee attack with advantage. On a successful attack, an enemy that is Large or smaller is knocked prone. You may then make a ranged attack with a summoned, magical dagger at a different enemy within 30 feet of you. On a successful attack, an enemy that is Large or smaller gains the Stunned condition until your next turn.
