1) If a caster casts a spell, and the target successful pass his saving throw, does the caster immediately knows that the target makes his save successfully?
2) Does a spellcaster knows even without seeing when the effect of his concentration spell ends?— Draconis (@DerynDraconis) January 28, 2019
A spellcaster doesn't automatically know whether a spell's target succeeded on a saving throw against the spell, but with most spells, the effects are perceivable on the target. #DnD https://t.co/B4HHWJTMQr

Thanks @JeremyECrawford!
And does a spellcaster knows (even without seeing) when the effect of his concentration spell ends?
ie: If I cast the Invisibility spell on the Rogue that goes alone inside a palace to kill his victim. When he attacks I feel that the effect of spell ends?— Draconis (@DerynDraconis) January 30, 2019
If you're concentrating on a spell, you know when that spell ends, whether you end your concentration willingly, your concentration is broken, or the spell ends in some other way. #DnD https://t.co/sQgmU1hlCQ

Hi Jeremy, how about with Zone of Truth? With no obvious visual/sensory indicators, it sounds like the caster might not know if the spell took hold, meaning they can't tell if the targets are being truthful? And if they can't, does that make the spell kind of pointless?

Zone of truth: "You know whether each creature succeeds or fails on its saving throw" (PH, 289). #DnD #TheRulesTellNoLies https://t.co/t4kdVtQKf6

When I face down a zone of truth, I plan on telling my truth in dance! They'll both know that I'm telling the truth, and not know what I mean. My hopes? Lead to a whole new school of art in Waterdeep in a hundred year quest to understand my answer!
