Revised Assassin

The purpose of this subclass is much the same as the preexisting assassin subclass but with a twist. This subclass is not as reliant on the surprise round, and focuses more on increasing the consistent damage of the rogue.

You focus your training on the grim art of death. Those who adhere to this archetype are diverse: hired killers, spies, bounty hunters, and even specially anointed priests trained to exterminate the enemies of their deity. Stealth, poison, and disguise help you eliminate your foes with deadly efficiency.
