Frontline Caster, Variant (5e Feat)
From D&D Wiki
Prerequisites: Ability to cast at least one spell
Through specializing casting spells in close quarter combat, you can adequately defend yourself on the front lines using quick defensive magic.
- Increase your Wisdom, Intelligence, or Charisma score by 1
- Being within 5 feet of a hostile creature doesn't impose disadvantage on your ranged attack rolls.
- You may calculate your armor class by using your spellcasting ability modifier instead of your dexterity bonus. If you are wearing armor, you must be proficient in that armor type to gain this bonus.
