@JeremyECrawford can giant crabs really grapple any size creature? No restriction in stat block.

— Grant Myers (@realgrantmyers) October 25, 2016

If a spell, class feature, monster ability, or other effect lets you target a creature and doesn't specify size, any size will do. #DnD https://t.co/vQBaMZ5b9v

@JeremyECrawford The PHB specifies grappling caps at one size larger. and larger creatures auto-succeed escape checks (w/o grappling feat).

— Nick Miller (@Millatron81) October 25, 2016

See the sidebar "Grappling Rules for Monsters" in the Monster Manual (p. 11). The size material in the PH is irrelevant to those rules. #DnD https://t.co/RlhIiKyPJd

@JeremyECrawford is it intentional that the giant crab can grapple anything, or just RAW?

— Grant Myers (@realgrantmyers) October 25, 2016

If we intend for a monster ability to have a size limitation, we note that fact in the ability. #DnD https://t.co/JgQJ5OIrcX

@realgrantmyers You're welcome. And thanks!

@JeremyECrawford Detect Thoughts: Does the target know the identity of the caster as a result of the save or just that the probing occurred?

— Ian (@CuttableSoup) October 28, 2016

If you didn't witness the casting of a spell, you don't know who cast it, unless a spell or other feature says you do. #DnD https://t.co/qzMHqX1jxj

@JeremyECrawford Can you clarify handling multiple stacked "advantage" bonus at once? Having "advantage" and "disadvantage" stacked?

The Player's Handbook delves into adv./dis. in detail (p. 173). In short: ∞ adv/dis = 1 adv/dis. Adv − dis = 0 #DnD https://t.co/XAMqSbaXtp

@quadhundArcane recovery has “once per day” language. Intentional? Yes.

@JeremyECrawford Can someone cast underwater?

— Enrique Delgado Torr (@enrikisinger) April 1, 2016

Being underwater doesn’t prevent spellcasting. #DnD https://t.co/pTg13iQ9T9

@JeremyECrawford Are paladins required to follow a Deity? I thought that their power came from their Oath and Conviction?

— Ambryn (@konafusion) October 5, 2016

Some paladins serve a god or a group of gods. Some paladins don't. #DnD https://t.co/PDKuqtt2iq

— Jeremy Crawford (@JeremyECrawford) October 5, 2016

@JeremyECrawford @konafusion If a Paladin doesn't follow a God, then what's the source of his/her divine power? Conviction?

— Faisal Saddique (@FaisalSaddique) October 5, 2016

"A paladin's oath is a powerful bond. It is a source of power that turns a devout warrior into a blessed champion" (PH, 82). #DnD https://t.co/Mqp3zEOlwv

@aus_maverick @FaisalSaddique @konafusionBlessed by whom though? 🙂 That's a question to be answered by you and your DM.

— Jeremy Crawford (@JeremyECrawford) October 5, 2016

@AardvarkBlue What I meant is that, e.g., a cleric could worship N gods equally, N > 1. E.G., Sovereign Host. Not always, or even often.
Indeed!
