Practice the Grim Art of Death
An Assassin's training focuses on using stealth, poison, and disguise to eliminate foes with deadly efficiency. While some Rogues who follow this path are hired killers, spies, or bounty hunters, the capabilities of this subclass are equally useful for adventurers facing a variety of monstrous enemies.
Assassinate
You're adept at ambushing a target, granting you the following benefits.
Initiative

Surprising Strikes
