Is it possible for a) a Warlock to lose the support of a Patron, similar to a paladin oathbreaker, or b) for a warlock to switch patrons?

@JeremyECrawford @SageAdviceDnD I’ve seen you and @mikemearls say it’s unnecessary for Warlocks to be on good terms with their patrons, and their powers can’t be stripped, but some class features mention “entreating” or asking the patron for help. Are those losable?

In D&D, advancing in level is the requirement for gaining your higher-level class features.

Some features have a story that can be read as imposing other requirements; the imposition of such requirements is in your and your DM's hands. Follow your storytelling bliss! #DnD https://t.co/Wpi56ZleBi

@JeremyECrawford most wall spells describe either 10 foot panels (force, stone) or that you can shape it anyway you want as long as it stays on the ground (wind). Wall of fire just states the wall or ring shape. Can you shape the wall like an L for instance?

The Wall of Fire spell in D&D can form a wall that is a straight line or a ring.

The fact that other wall spells can have other shapes has no bearing on Wall of Fire. Each spell governs only itself. #DnD https://t.co/9wSZWXNwHe

@JeremyECrawford Hey I'm loving the wild magic barbarian! Wanted to make sure their ability actually uses a d3 or is that a typo?

— Masonlock (@MasonLopes1) November 19, 2020

D&D does use the d3. It appears in some magic items, in the Wild Magic barbarian, and elsewhere. For guidance on using a d3, or even a d2, check out the "Game Dice" section of the Player's Handbook (p. 6). #DnD https://t.co/MGqKAWGnOc

@JeremyECrawford Is it true there is no longer a "Hold" action in 5e? I know my Players virtually live by it, but I've seen many sources say you can no longer hold your action till later in the round.

— Richard (@Sepulcher67) August 10, 2020

There is no Delay/Hold/etc. action in D&D. When it's your turn, you either act or don't act.

If you decide to do nothing, I recommend taking the Dodge action.

If you want to act later in the round, use the Ready action. #DnD https://t.co/4Bx6cNvj0q
