@JeremyECrawford Do a Warlock's Eldritch Invocations still function if he/she was under the effects of a polymorph spell?

— FreelanceNerfHerder (@Kevin_Boyd_) September 13, 2017

While you're under the effect of the polymorph spell, you use the stat block of your new form, not your character sheet. #DnD https://t.co/NHYAjyzy9d

Does this apply to mental stats? I though only physical ability stats changed?You're thinking of Wild Shape. Polymorph changes all your stats.

— Jeremy Crawford (@JeremyECrawford) September 13, 2017

I assume this means, assuming a form that can still cast spells, that DC’s, spell attack bonus, etc.. all change?That's correct. You're playing with the stat block, not your character sheet. Set the latter aside.

Do the monk’s ki empowered strikes function when inside an antimagic field?

The Ki-Empowered Strikes feature says a monk’s unarmed strikes count as magical. That magic is suppressed in an antimagic field. #DnD https://t.co/UKTq0DNGvw

Does a paladin’s smite ability get suppressed? Nowhere does it read it is a magical ability.

Divine Smite is fueled by spell slots—raw magic. See the latest Sage Advice Compendium for more on this topic: https://t.co/7uBLqNdn4G #DnD https://t.co/LKLS2lqLNk

So magic initiate would not work with smites? Since it simply gives you spell casts, not necessarily slots?That’s correct.

— Jeremy Crawford (@JeremyECrawford) September 13, 2017

Does a successfully countered spell still use up the spell slot?Yes.

@mikemearls If a human rogue uses an action to Dash (60 ft.) and then Cunning Action to Dash, do they move 90 ft. or 120 ft.?

— Sam Stockdale (@BitterChivalry) July 31, 2017

That's correct. Dash doesn't increase your speed.

@mikemearls @ChrisPerkinsDnD @JeremyECrawford Do fire elementals keep doing damage to unconscious creatures when they set them on fire?

— caleb morrison (@CalebTeen) September 19, 2017

An effect tells you if it ends when an affected creature falls unconscious or dies. The fire elemental's text doesn't say such a thing. #DnD https://t.co/SBYw9UTtzf

The PHB and DMG are decent references, too. 😉 They sure are! That’s why they’re in the first section of the Sage Advice Compendium. 😉

@JeremyECrawford Are the effects of "bane" spell and "cutting words" cumulatives?

— Xabier Cantalapiedra (@XabierCantalap2) September 20, 2017

And see "Combining Magical Effects" in the Player's Handbook (p. 205).
