2nd degree Rapid Current Reaction
Pointing your weapon at your foe you challenge them, forcing them to lower their defenses so you can launch an attack of your own.
At the end of your turn, you can use your reaction to gain an expertise die to your AC against one creature you can see within reach. This increase to your AC only applies to the chosen creature and ends at the start of your next turn.
If the creature misses with one or more attacks against you before the start of your next turn, you can make a melee weapon attack against it.
