Does cover affect saving throws?

@RobinBergmark @JeremyECrawford @mikemearls – Does cover affect saving throws? I might give a cover bonus if the caster rolled to hit.

@GoblinMonk @RobinBergmark @JeremyECrawford believe it gives a bonus to Dex saves #WOTCstaff

Cover can affect Dexterity saving throws. Take a look at the rule (PH, 196). #DnD https://t.co/KsQf1FScNw
