@xanderh2404 Should multiclass 3rd casters round up or down? Single-class rounds up, but multiclass rules says to round down. A multiclass character follows the rules for multiclassing.

@xanderh2404 this means that EK multiclassing wizard doesn’t advance spell slot progression. Intended?
An EK is at least a 3rd-level fighter and therefore contributes at least 1 level to multiclass spell-slot advancement.

@xanderh2404 20 EK has the same spell slots as a 19 EK / 1 wizard. This is what I meant. That's correct.

@xanderh2404 That basically makes the dip worthless, though. Doesn’t feel well thought out, to be honest. If 3 cantrips, 6 1st-level spells, Ritual Casting, Arcane Recovery & a spellcasting focus are worthless to you, do avoid them.

— Jeremy Crawford (@JeremyECrawford) February 18, 2016

@JeremyECrawford actually, on that note, would the Arcane focus work with EK spells as well?

— alexander Hvilshøj (@xanderh2404) February 18, 2016

An Eldritch Knight casts wizard spells. With a level in wizard, you can use an arcane focus with those spells. #DnD https://t.co/fwh1C9uTHy

@Hedgeson991Do swashbuckler rogues get to add their dexterity modifier to offhand weapon attacks while two weapon fighting? I'm curious, what feature in the Swashbuckler is prompting you to ask about two-weapon fighting?

@Hedgeson991 The sidebar provides tactical advice. That is all.

@yr43lHey, if a caster polymorphs himself, and then takes damage in the polymorphed form, does he need a concentration check? Yes.

@JeremyECrawford Can a spell like Macimillians Earthen Grasp or Telekinesis which targets 1 creature but u can change to another be Twinned

— Carmine (@nirvanstryder) February 2, 2016

Can a spell at its current level target more than one creature? If yes, you can't twin it. #DnD https://t.co/zDJSO5oUtx

@JeremyECrawford @nirvanstryder that seems vague still to me. At casting, earthen grasp can only target one, but can be moved later…

— eric moss (@eerongal) February 4, 2016

A spell like Maximilian's earthen grasp doesn't target anyone at first. You create a thing, which then targets. #DnD https://t.co/meeJsGJlkO

@andreasfr1 @JeremyECrawford Find Familiar gives form to a spirit. I would not be surprised if a familiar is not considered a creature.

— Steven Connor (@Mazoshi1987) October 27, 2016

A familiar is a creature. #DnD https://t.co/7QlkT7xupF

@JeremyECrawford Does something that makes disadvantage on ability checks (with no mention of skill checks) also impact skill checks?

— Uranium Dragon (@uraniumdragon) September 20, 2016

Some ability checks use a skill. Some don't. "Skill check" isn't an official term but can be short for "an ability check with a skill." #DnD https://t.co/Warz6DkYk4
