Witchcraft

You are a practicioner of the dark arts, concocter of strange potions and medicine, and a follower of the eldritch gods, fiends, or old gods. People seek you out when they require help or information about love, sickness, or death.

Prerequisite: Any spellcaster class.

Benefit: You have two features:

Reroll Ability. You can reroll an ability check that involves the skill Arcana, History, Medicine, Nature, or Religion, or any ability check that uses the Herbalism Kit. You must use the result of the second roll, even if it is lower.

Impose Saving Throw Disadvantage. When you cast an enchantment or necromancy spell at a creature, you can take a bonus action and impose disadvantage to the creature's saving throw roll. Once you use either feature, you cannot use any of them again until you finish a long rest.
