Would it be possible to have something LIKE a familiar? Say a homonculus and a familiar?

In D&D, a limitation on X has no bearing on Y, unless a rule says otherwise.

For example, if a rule says you can have only one familiar (X), that rule is irrelevant to the number of other NPC companions (Y) you might have. #DnD https://t.co/mZvaHqUEZe

A more general question. Why are familiars in 5e far less mechanically important for a non-warlock caster compared to previous editions? Design intent? Player feedback? oversight? #DnD By "mechanically important," do you mean a class feature dedicated to familiars? If so, only one edition of the game had such a feature: 3rd edition. We went with the game's more-established tradition for 5th edition.

whoever is the main creature wrangler at @Wizards_DnD: would you consider a porcelain golem to be a clay golem, stone golem, or its own new type?I'd go with stone

When designing a TRPG mechanic, answer these three questions:
1. What question does it answer?
2. When during a session does it come into play?
3. Why is this a new rule, rather than a repurposed existing one?

I really, really, really wish tabletop design had an even stronger tradition of emphasis on speed of play. I don't *care* if your rule is "super-accurate" and takes a million factors into account, if I have to use a million modifiers every time. https://t.co/7RRXbRUMKL

Trad RPG designers – THIS!

Indie folks you already have this figured out by cleverly not trying to do everything at once all the time. https://t.co/SycfqxlbSt

You know you’re playing Champions when rounds can be measured in 1/13th pieces.

#3 is a very good question Probably the most important lesson that @JeremyECrawford teaches – it’s his mantra.

Hey @matthewmercer @mattcolville @mikemearls could you boost the signal for a long-time DM, #smallyoutuber and aspiring worldbuilder? Sometimes hard to be seen.https://t.co/IBS2bMoqsN #dnd

Completely! It’s just irritating when I say “there is a problem with this system” and people say “just change the rules!” I don’t wanna fix a leak I wanna know why my transmission is defective. It’s hard to have those conversations in public – everyone has different limits and goals. I’ve been thinking about streaming playtest games, then doing a vid where we break down what went wrong.

— Mike Mearls (@mikemearls) August 5, 2018

We don’t have a critical language or framework for breaking down why we design. The how and what have been solved… like a billion times. People focus on that.

can I cast a first level or higher spell (eg Magic Missiles) and, if the situation permits, cast a reaction spell (eg Shield) in the same round of combat?Yes
