The Shield Master feat includes the following benefit:
lf 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.
This sounds great, until you realise that spells like Fireball (the vast majority of spells that trigger a Dexterity saving throw) target a point, not a creature.
For a spell like fireball, the target is the point in space where the ball of fire erupts.
So what spells are there (WotC published 5e material only) that target a single creature and require that creature to make a Dexterity saving throw?
