@JeremyECrawfordUncaught erratum? MM says oni can Change Shape into Large giant OR back into true form—but true form IS a Large giant. Or does it mean it can Change Shape into OTHER large giant forms, e.g., ogres, ettins, trolls?

An oni's true form is oni. #DnD https://t.co/BhsqQQ0cxF

@mattdomvilleIOW: Spells known for multiclass characters are determined by individual class in all respects, including changing spells? Yes.

@JeremyECrawford What happens when you cast Revivify on someone who has been killed by a shadows Strength Drain? Does it even work?

— John Welker (@Saga_Welker) December 6, 2016

If a shadow's Strength Drain creates another shadow, there's a 1d4 hour delay before it happens. You can raise the person in that time. #DnD https://t.co/yXsvk7xU4j

@JeremyECrawford But will the character have 1 hp and 0 Str or some other combination with Revivify?

— John Welker (@Saga_Welker) December 6, 2016

Revivify restores you to life with 1 hp. It doesn't remove ability reduction. Ready greater restoration to save the person with 0 Str! #DnD https://t.co/1oOiW0B3dA

@JeremyECrawford Surrounded by enemies, cast levitate on myself. No opportunity attacks when rising 1st 20 ft. because not move, right?

— Eric Green (@quadhund) November 8, 2016

Read the 3rd paragraph of the opportunity attack rule (PH, 195). Using your action to move doesn't spare you from opportunity attacks. #DnD https://t.co/LfhnPnl9pH

@thomas_conners“Remember that you can take only one reaction per round.” Why is the only place this is mentioned the entry for Ready? Take a look at the rule for reactions (PH, 190).

@thomas_conners No mention of a hardlimit of 1/round. It says they reset at the start of your next turn. I ask because of Theif’s Relfex’s. There's no "they." You take one, and you can't take another till the start of your next turn.

@quadhundInstrument of the Bards. Disadvantage against charm spells ONLY cast from instrument’s list OR charm spells cast w/ item? Take a look at the last sentence of the third paragraph.
