@JeremyECrawford Can you target someone being grappled with Otiluke's resilient sphere (in order to protect them)?

Being grappled doesn't prevent you from being targeted by a spell. #DnD https://t.co/5w8abuFLkQ

@JeremyECrawford Two thumbs up! ORS to save people being grappled to death is an oldie but a goldie.

This is an awesome, classic use of Otiluke's resilient sphere … #DnD https://t.co/hZYjKxcoX6

@JeremyECrawford @Dan_Dillon_1 how would this interact with a swallowed creature? Discomfort for beast eating them?

A spell can't target someone who has total cover, unless the spell's description says otherwise. #DnD https://t.co/96JgWZGLrx

@JeremyECrawford Does the 5E Warlock spells known limit factor in Mystic Arcanum? As a level 11 Warlock could they know 11 1-5 spells & 1 MA

— Joshua Watkins (@KlarterBlue) November 20, 2016

Mystic Arcanum has no relation to the number of spells a warlock knows with Pact Magic. #DnD https://t.co/BmcJuMtMIs

@JeremyECrawford What happens when you cast "Hallow" on a place that has already undead on the location?

— Lodewijk Boute (@Lodewijk_Boute) October 26, 2016

The hallow spell prevents undead from entering its area. If they're already there, they already entered it. #DnD https://t.co/mGMyccTx1E

@The_Indoorsmen Precisely.

— Jeremy Crawford (@JeremyECrawford) October 26, 2016

@Lodewijk_Boute You're welcome!

— Jeremy Crawford (@JeremyECrawford) October 26, 2016

@JeremyECrawford still only 1 non-cantrip allowed per turn?

— Tinker-TDC (@TubaDanCross) October 20, 2016

The number of spells you can cast per turn is determined by casting time and slots, not the level of the spell. #DnD https://t.co/Iu0S4aSb9o

Forgive me if you have answered this before but does the counterspell work against wands? And the like?

Counterspell targets a creature casting a spell, no matter the source of the spell (the creature, an item, etc.). #DnD https://t.co/N9c5Bt9QWG
