@JeremyECrawford Also, with Rapid Strike: You sacrifice advantage for an additional weapon attack. Can the additional weapon attack have advantage? Or can neither attack benefit from advantage? I assume the latter.

Rapid Strike doesn't prevent the bonus attack from having advantage. #DnD https://t.co/1KQXJ6gyV4

@SageAdviceDnD @JeremyECrawford can the weapon from the shadow blade spell be chosen as a kensei weapon? The spell says the blade counts as a simple melee weapon. I am a bit confused and am wondering if it works. #DnD

The Path of the Kensei feature says which weapons qualify as kensei weapons. The shadow blade meets the qualifications. #DnD https://t.co/Ydh4dK7kQx

@JeremyECrawford does the shadow blade from the eponymous spell add dex/str as appropriate when dealing damage or is it only the flat 2d8 psychic damage?

— PKMN Trainer Tom (@IFlyDragons) November 14, 2017

The shadow blade spell creates a weapon, and the spell doesn't tell you to ignore the general rule on making weapon attacks (PH, 195). You therefore add the appropriate ability modifier. #DnD https://t.co/gAmiVnM5jP

@JeremyECrawford Is the intent of the Shadow Sorcerer to be able to cast Darkness by expending any spell slot, including first level ones, oronly with second level slots or higher?

— Rystefn (@Rystefn) November 11, 2017

The Eyes of the Dark feature doesn’t change the rule on spell slots. You must use a slot of the spell’s level or higher. #DnD https://t.co/UrMRhVOzzx

if I can’t use heavy weapons as kensei weapons, how am I supposed to have my cool Naginata (Glaive) monk?If naginata use is your priority, I recommend playing a fighter.

@JeremyECrawford Please answer! I'm tired of spamming this. If I have a Pegasus from Greater Find Steed then true polymorph it into a Silver Dragon Wyrmling, the wyrmling still has a lifelong bond and has a telepathic link, correct?

— s (@sethmhilliard) November 25, 2017

One spell doesn’t end another spell’s effects unless (a) one of them says it does or (b) a general rule says it does. For example, no rule says polymorphing your supernatural steed has any effect on your bond with it. #DnD https://t.co/70yFEyUDGi

According to this tweet https://twitter.com/JeremyECrawford/status/931621590730653696 … it would seem that the effects from Find Greater Steed are suppressed while the creature is not one of the possible forms. It’s still your steed. Polymorphing it doesn’t change its magical relationship to you.

— Jeremy Crawford (@JeremyECrawford) November 27, 2017

If Polymorph suppresses charm, and replaces all game statistics, the statistics of the creature from a Greater Find Steed spell (including int, ability to speak, telepathic communication, etc.) should be suppressed. The bond between the paladin and the steed isn't one of the steed's game statistics.

— Jeremy Crawford (@JeremyECrawford) November 30, 2017

Frankly, I was a bit surprised when you ruled that Polymorph would suppress the effect of Charm Person, since I didn’t think that a condition was a part of creature statistics and since Charm Person does not have any continuous check for creature type. To be clear, I haven't ruled that polymorph suppresses charm person. I said there's no rule and gave a rule of thumb (a house rule) you might want to use. There is no official ruling on this point.

Can a Mastermind Rogue use the Help action as both a normal Action & a Bonus Action in the same turn to assist 2 different PCs in combat?Yes.

@JeremyECrawford is summon greater demon restricted to fiend (demon)? I really want to summon a nightmare mount for my eldritch knight because it cool.

— Skelaton_lor (@Skelaton_lor) November 20, 2017

Summon greater demon means demon when it says "demon." #DnD https://t.co/6x5CW0zHpr

— Jeremy Crawford (@JeremyECrawford) November 21, 2017

But do you deny summoning a Nightmare to ride is pretty damn cool? The undeniable coolness of nightmares has no bearing on the function of that spell. 🤓
