• 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 opportunity attack. The spell must have a casting time of 1 action and must target only that creature.

You can speak, read, and write Common, and Elvish.
