@JTtheBeardless @JeremyECrawfordIf a player readies the attack action and has extra attack, do they hit once, or does extra attack activate? hit once – extra attack specifies it works when you use the Attack action on your turn

@DafatmofoCan you use counter spell against another counter spell? #dnd5e yes

@ChrisPerkinsDnD Watching Acq. Inc. Episode 4, and I have to ask:

Are the Zhentarim basically the Mafia of the Forgotten Realms?

— Matthew Ryan Gostick (@ComplexityofOne) June 29, 2016

Pretty much. https://t.co/w0lpsfNbG3

@ChrisPerkinsDnD So…weird question. My players wants to raise a goblin army and they asked me about…breeding goblins. So…yeah. Help?

— Kordwar (@Kordwar) July 6, 2016

Tell them that's not the kind of "adventure" you signed up for. Besides, we all know "goblin armies" are weak sauce. https://t.co/rtGyOpPKLF

@ChrisPerkinsDnD Any advice for when your players want to roll a check every time you speaking? Rolling excessive perception/arcana checks?

— Seth Đennison (@SmilingJack2x) July 9, 2016

Blow em off.

Player: "I rolled a 17 on my Arcana check!"

DM: "That's nice, but I didn't ask for an Arcana check." https://t.co/SBMkBY0mo8

@ChrisPerkinsDnD It's not that they flat out do it, they just won't stop asking after every time I describe a room or environment. 😧

— Seth Đennison (@SmilingJack2x) July 9, 2016

Tell them to stop interrupting you. https://t.co/eWC1DCNnhc

@ChrisPerkinsDnD How do dragon breath attacks work underwater?

— Wait…What? (@davoerlo) July 24, 2016

DM's call. For example, fire breath could be hot enough to burn through water or become scalding steam. #WOTCstaff https://t.co/Lc8Dg3SY7j

1. Incoming tweets about D&D traps and locks, because some old-school traps are grinding on my nerves a little, while others are inspiring.

— Chris Sims (@ChrisSSims) August 10, 2016

2. When you add a trap to an adventure, think about its effect on play. Will it cause grinding caution in the players? Do you want that?

— Chris Sims (@ChrisSSims) August 10, 2016

3. Think about how it works, how it can be found, and how it can be disarmed. You need to be able to describe these aspects.

— Chris Sims (@ChrisSSims) August 10, 2016

4. Think about what failure to disarm means. Maybe it's just wasted time, but it could mean lack of safety despite perception of it.

— Chris Sims (@ChrisSSims) August 10, 2016

5. Also, think about how the trap affects those who placed it. Smart creatures don't place traps likely to harm them in the future.

— Chris Sims (@ChrisSSims) August 10, 2016

6. That's why something like glyph of warding is so useful.

— Chris Sims (@ChrisSSims) August 10, 2016

7. If your world has ample magic, a mechanical trap shouldn't be more resource intensive than that spell, unless its makers did it for fun.

— Chris Sims (@ChrisSSims) August 10, 2016

8. (Like dwarves and their crazy vaults, but I digress.)

— Chris Sims (@ChrisSSims) August 10, 2016

9. And, when it comes to locks, one question is primary. Where is the key?

— Chris Sims (@ChrisSSims) August 10, 2016

10. The answer could be the key is nowhere. But if someone in the dungeon needs to open that lock regularly, that answer is likely wrong.

— Chris Sims (@ChrisSSims) August 10, 2016

11. Also, most locks are just a time sink to pick, and they become a dramatic interlude only if the time to open actually matters.

— Chris Sims (@ChrisSSims) August 10, 2016

12. Too many of these elements in an adventure makes it seem arbitrary and can even make playing less fun.

— Chris Sims (@ChrisSSims) August 10, 2016

13. One more thing (as always): Why was the trap created? Why is this lock here?

— Chris Sims (@ChrisSSims) August 10, 2016

@ChrisSSims hwvr locked vs unlocked is narrative, gives the party information about the relative importance and security of a given area.

— Ken Walter (@redkatartist) August 10, 2016

Sure. It's okay for a lock to serve a practical purpose. https://t.co/K7Z3vifLAh

— Chris Sims (@ChrisSSims) August 10, 2016

Traps should be specialty interactions for players that are into such things; if your group isn’t up for this, don’t https://t.co/TxSEVeDblh

— (((Georg Mir))) (@GeorgMir) August 10, 2016

I'd say minimize, but I agree in general. https://t.co/nRf1j293l9

@JeremyECrawford is it the intention of the Repelling Blast warlock feature to interact with any size creature and provide the knockback?

— Nathaemius Varrowe (@dmvarrowe69) July 1, 2016

Repelling Blast works on a creature of any size. The feature would tell you if there was a size limitation. #DnD https://t.co/6eZbh9tF7R
