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?

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.

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.

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.

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

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. 🤓

I have a player who wants to use the Forge Cleric Channel Divinity option to create plate armor in 15 separate pieces. Is this a stretch or misuse of the ability? It feels like a violation of the spirit of the ability to me.

Originally Spectral Defense gave half damage. Now offers resistance, which prevents stacking with items offering resistance. Thus making this much weaker than Uncanny Dodge which is at a much lower level. Intended or oversight?We didn't change it on accident. Uncanny Dodge is the same level for a Hunter ranger. UD requires seeing the attacker. SD does not.

@JeremyECrawford #DnD PH 187 states new language/tool prof. takes 250 days. XgtE 134 states ten workweeks. Is this an errata?

The "Downtime Revisited" section in Xanathar's Guide is, like all the rules in its chapter, optional. If you decide to use the option, you're using it instead of the downtime rules in the PH and DMG. #DnD https://t.co/S90aKID6uP

Physical copy on its way to Renton. I think this is an important discussion & issue for D&D. Thank you in advance for your time. pic.twitter.com/7JpSwakKqI

Thank you for the letter. As noted in the introduction of "Downtime Revisited," those rules are designed as an alternative to the downtimes rules in the PH and DMG. They're not meant to be used together.

@JeremyECrawford Hey, for the new Storm Herald barbarian, there isn't a size limit on the effects the storm's do. Does this mean any size creature is effected by things like being knocked prone when I activate my storm next to them?

— 1I11I1II1II1I1 (@i11_ii1) November 27, 2017

Creature size is irrelevant to a rule unless that rule, or another relevant rule, says otherwise. #DnD https://t.co/yK49GsLlcf
