Grudge-Bearer (RZS)

You have a deep and burning hatred for a particular kind of creature. Choose a foe to bear the burden of your wrath: aberrations, beasts, celestials, constructs, dragons, elementals, fey, fiends, giants, humanoid, monstrosities, oozes, plants, or undead. If you select the humanoid option, you must declare the specific type of humanoid race (orcs or goblins, for example) that tends toward an alignment opposite to yours. You will need to get GM's approval to have a grudge against any of the common player character races. Once your grudge is selected, you gain the following benefits: 

• Increase STR or CON by 1, to a maximum of 20
• During the first round of any combat against a chosen foe, your melee attack rolls against any of them have advantage.
• When you bring a chosen foe to 0 hit points, you can use a bonus action to make a battle cry. You regain hit points equal to half the size of one of your hit dice from your battle cry and friendly creatures within 30 feet who have the Grudge-Bearer feat gain advantage to their next melee attack.
