Prof in Perception

Warcaster:
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'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.

 

Arcane Recovery:
You have learned to regain some of your magical energy by studying your spellbook. Once per day when you finish a short rest, you can choose expended spell slots to recover. The spell slots can have a combined level that is equal to or less than half your wizard level (rounded up), and none of the slots can be 6th level or higher.
