Master of One-Handed equipment

You can interrupt another combatants turn with 2d20 rolls that equal 26.

You then deal half your normal damage. Each time you do this, you deal half of previous damage. (minimum is 1)

You can throw your shield and have to make a DEX saving throw to get it back.

If thrown at an ooze, your shield will go through and bounce off a wall and return, no need to make a saving throw.
