You have practiced casting spells amid combat, granting you the following benefits:

• Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.
• You have an Advantage on Constitution Saving Throws that you make to maintain your Concentration.
• When a creature provokes an Opportunity Attack from you by moving out of your Reach, you can use your Reaction to cast a Spell at the creature rather than making an Opportunity Attack. The Spell must have a casting time of one Action and target only that creature.
• You can perform the Somatic Components of Spells even when you have Weapons or a Shield in one or both hands.
