You have practiced casting spells in the midst of combat, learning techniques that grant you the following benefits:
- You have advantage on Constitution saving throws that you make to maintain your concentration on a spell when you take damage.
- 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 moves out of your 5 ft. reach, you can use your reaction to cast a spell at the creature. The spell must target only that creature.
