Shield Master [Armor}

Requires Shield Bash Feat

If you aren’t incapacitated, you can add your shield’s AC bonus
to any Dexterity saving throw you make against a spell or other
harmful effect that targets only you.
In addition, 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.
