Retracting Snapping Turtle

Prerequisites: Moderate Snapping Turtle

Your proficiency with a shield and finesse weapon to work in tandem has given you reactionary defensive abilities in combat. You now gain the following:

• If you are subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you can use your reaction to take no damage if you succeed on the saving throw, interposing your shield between yourself and the source of the effect.
• When you are wielding a shield and finesse weapon with which you are proficient and another creature directly hits only you with a damaging attack, you can use your reaction to add your proficiency bonus to your AC for that attack, potentially causing the attack to miss you.
