@JeremyECrawford One of my player is using polymorph at himself to be a TyrannosaurusRex.Isnt he abusing?Is that the intention of the spell?

You can cast polymorph on yourself, provided you can see yourself. #DnD https://t.co/MQ0FzPkrYX

@JeremyECrawford You can always see your hand, for example, Do you mean you need to see the whole body in order the spell to work?

— Enrique Delgado Torr (@enrikisinger) February 27, 2016

To see yourself, just look down. Something like blindness or darkness can prevent it. #DnD https://t.co/gfyXUwMhhi

@JeremyECrawford @aleque_b The dual wielder feat bypasses that restriction though, right?

— Gerbub (@userZynx) November 7, 2016

The 2nd benefit of the Dual Wielder feat does, indeed, do what it says—bypass the need for 2-weapon-fighting weapons to be light. #DnD https://t.co/NvWcBUUIvT

@JeremyECrawford Re: PHB Errata. Do I understand correctly that EKs can retrain their 3rd level spell in any school but ATs still cannot?

— Edward Krusling (@EdKruze) October 25, 2016

Like an Eldritch Knight, an Arcane Trickster can retrain their 1st-level spell from any school. (An unintended omission.) #DnD https://t.co/DLvg47Ig9l

@Browncoat182 @EdKruzethank you I thought these classes were limited by certain schools of magic. Some of their spells are limited, but others aren't.

@ElliottcFarmer @ChrisPerkinsDnD @mikemearlsIf a creature can breath underwater, can it perform the verbal component for spells underwater Yes.

@JeremyECrawford does SR have >1 dmg roll? difference between SR and MM is PH 196; simultaneity of dmg. otherwise seems 1 roll for both

Different attack rolls = different damage rolls. #DnD https://t.co/RentPgtZBd

@JeremyECrawford Phantom Steed: Regardless of how the spell ends, it lasts for one more minute as it fades away, correct? Can be ridden?

— Charles Sturges (@CharlesSturges) October 19, 2016

RAW: you can ride a phantom steed only during its duration, not during the 1-minute fade. But a DM breaks nothing by ruling otherwise. #DnD https://t.co/Dk9I5ADgJy

@JeremyECrawford I hope u can help. If STR 10, Item that increases STR (Ioun Stone) & item that sets Score (ogre gauntlets) stack for a 21?

— Héctor A Toledo H (@KorhilTohru) August 23, 2016

The Ioun stone specifies that it doesn’t raise your ability score above 20 (DMG, 177). #DnD https://t.co/WQHChoxKYZ

@JeremyECrawford A psychic resistant enemy rolls 40 psychic damage against a Thought Shield-ed warlock. Does the enemy lose 40, 20 or 10 HP?

— Millstone85 (@Stonemill1985) November 16, 2016

Thought Shield doesn't deprive your foe of resistance to psychic damage. (In the example, the resistant enemy takes 10 psychic damage.) #DnD https://t.co/YSfCu1HCIJ
