does the Lucky feat replace a roll even if the text doesn’t explicitly use the word replace? Some of your previous tweets imply yes.The Lucky feat does give you the ability to replace a roll, and you decide whether to make the replacement.

@JeremyECrawford Regarding Mace of Terror, (DM Guide, p. 180) "roll 1d3 to regain charges". For those (all) of us that dont have this particular plastic geometric phenomenon, what would you say would be an acceptable substitute

Once in a while, the mythical d2 and d3 appear in D&D rules. If you encounter them, the "Player's Handbook" can guide you in handling them. Check out the section called "Game Dice" on page 6 of that book. #DnD https://t.co/6IAg5LuiMU

@JeremyECrawford You’ve previously said that game features that require a weapon refer to items on the weapon table in the PHB. With that being said, does the Tentacle Rod count as a weapon for these features? The description states it is a magic weapon.

— DMDanDanFielding (@DMdandanfieldng) February 14, 2019

If a rule says something is a weapon, that thing is a weapon, and it qualifies for other rules that require a weapon.

For example, the tentacle rod's description says, "This rod is a magic weapon." That means it's a weapon. #DnD https://t.co/nGwNXoFidS

No problem! 😀

the ruling of centaurs and lances is as silly as the shield bash errata. Neither of them make any sort of sense. Shield Bash has received no errata.

If a DM would like a centaur to be considered on a mount all the time, the DM is free to make that decision. But by rule, the centaur isn't permanently mounted.

@JeremyECrawford If I am a Warlock and I use an invocation to cast a spell that's not on the Warlock list (such as Levitate, Confusion, or Slow) requiring a save, does it use my Warlock spell save DC? Also, can such a spell benefit from Rod of the Pact Keeper?

The spells you cast through the Eldritch Invocations feature are meant to be warlock spells for you. #DnD https://t.co/ysQUzKLpEe

@JeremyECrawford If using your familiars senses and the familiar is destroyed do you still need to use an action to return to your own senses?

— Colin Mangan (@cgmangan) February 21, 2019

The find familiar spell requires you to take an action to use your familiar's hearing and sight, instead of your own. You automatically return to your own senses at the start of your next turn. #DnD https://t.co/vIGkKhh0sr

@JeremyECrawford Question: A Night Hag is in a coven with two Sea Hags. Do the hags have access to shared spellcasting if the Night Hag goes ethereal but still within 30 feet?

— Beaumont Sebos (@BSebos) February 21, 2019

If two people are on different planes of existence, they are infinitely far away from each other. For example, if I'm on the Material Plane and you're on the Ethereal Plane, we're not within 30 feet of each other. #DnD https://t.co/gj9b0672gT

What if the hags are in love? Love crosses all distance. But does love cross the phlogiston?

— Scott McElhinney (@Paladinnpajamas) February 22, 2019

Love can overcome any barrier! 🥰 https://t.co/shdBr8iLuD
