Air Assassination lets you leap from a ledge or rooftop onto a target. It is free from the start and earns XP for Assassin-style kills.
Air Assassination sits at position 4 of 19 in the Stealth tree. Air Assassination costs no skill points. The twins learn it during Sequence 1. Jacob and Evie each have their own skill tree, so you buy Air Assassination once for each twin.
