Peter Paul the Merry

Whether by mighty cleave, deft riposte, or smart sharpshooting, you enter the battlefield as a one-man army. Whenever you successfully attack an opponent within your reach, you may make a single attack as a bonus action in the round against a different opponent within a personal space of your victim, at disadvantage.

You've developed a uncanny ability to analyze the sensory makeup of food and drink. When you sniff or taste a meal as an action, you can determine its exact composition, and whether it's been corrupted in some way. (The quantity you taste does not harm you.) For each round you concentrate on the flavor, you may determine one mechanical reality. In the case of a poison, examples of mechanical realities include the type of poison, the harm it inflicts, or its onset and duration.

In the party, you take on the role of the steadfast leader, always putting the safety of your allies first. When you lead group action, you are not penalized for shouldering the burden of multiple piggybacking allies. Alternatively, if you are leading the action in a scene check, you may reroll the dice in any one of the acts, once per session.

You steel your soul against otherworldly peril, whether by the grace of your patron or sheer force of will. If you are subject to a source of attribute damage, you may make an opposed check as a reaction (matching the attribute of the check that precipitated the damage) to a cancel the damage, with advantage. In lieu of protecting yourself, you may confer the benefits of this stance to a target by touch.

Your wide-ranging interests are as comprehensive as they are exhaustive; some would call this genius, but you call it simple curiosity. When making a check involving a Domain Knowledge skill, you may substitute the specialty for a related field for 1 MP (with the GM's approval); a polymath proficient in Domain Knowledge (Demonology) could be proficient in Domain Knowledge (Witchcraft), as an example.

Your weapon thirsts for vengeance as if it has a mind of its own. Any time you fell a foe, you may make an additional attack as a bonus action against another foe within a melee space of you.

The thrill of the fight only emboldens you, and each success fills you with renewed vigor. Whenever you explode a die by rolling natural 6 on a d6, you recover 2 MP.

For you, the shield is a natural extension of your body and a weapon in its own right. As a reaction, you may parry with your shield as a bonus action in addition to any other parries or attacks you have in the round.
