@JeremyECrawford @mikemearls If a character multiclasses into wizard, how do you handle not having a Spellbook immediately? The PHB says you start with 6 level 1 spells in your Spellbook, so do you not have any spells at all? Do you prepare what you can and transcribe later? #DnD

The wizard's Spellcasting feature says you have a spellbook with six 1st-level wizards spells in it of your choice. That means you have a spellbook with those six spells in it. Work out with your DM how you acquired that wondrous book. #DnD https://t.co/zmPtj10GOg

@mikemearls @JeremyECrawford @ChrisPerkinsDnD @SageAdviceDnD for the purposes of the Shapechange spell, is your characters proficiency bonus a class feature? #DnD #SageAdvice #SageAdviceDnD

While you're under the effect of the shapechange spell, you use your proficiencies, including your proficiency bonus, except when the stat block of the new form has a modifier (proficiency bonus + other modifiers) that's higher for a proficiency you have. #DnD https://t.co/LOZpohZsW7

You know what I'd like to see the next printing of the #MonsterManual? An index of monsters that one might find in similar environs. Like the aboleth and chuul, for example. Make newbie DMing #DnD a little easier.

What say you, @JeremyECrawford & @mikemearls?

Eager to see monsters organized by environment? Take a look at appendix B in the “Dungeon Master’s Guide,” where there’s a section called “Monsters by Environment.” #DnD https://t.co/M8ZURXjXkW

@JeremyECrawford does the necromancer's grim harvest activate when an animated undead makes a kill?

A creature you summon/create/animate with a spell is not a spell. It was summoned/created/animated by a spell. #DnD https://t.co/bUkJ9JlxPU

This is totally inconsistent with the ruling that a Rashaka is immune to Shillelagh and magic stone. Neither of those spells involves summoning, creating, or animating a creature.
