Prerequisite: The ability to cast at least one spell
You're an experienced battle caster wich grants you these benefits:
- When taking damage, you get advantage on Constitution saving throws to help you maintain your concentration on a spell.
- You can perform the somatic components of spells even when you have weapons or a shield in one or both hands.
- When a hostile creature's movement provokes an opportunity attack from you, you can use your reaction to cast a spell at the creature, rather than making an opporunity attack. The spell must have a casting time of 1 action and must target only that creature.
