@josh_watson it must be from your spellbook – part of scribing a spell is learning and understanding it well enough to prepare it

@ovnen @ChrisPerkinsDnDwrt Cube of Force, does undead (eg zombies, ghouls) count as living or nonliving matter? I'd say nonliving.

@West_Thijs_23Thanks! a bit worried about the explanation on the lucky feat. A disadvantage becomes a supper advantage with this feat.
Here's one way to think of it: when you're most down on your luck, fortune smiles upon you.

@pliskavica @JeremyECrawfordDo effects such as Bend Luck imply that players know the results of enemy rolls even if the rolls are secret? in general, err on the side of announcing a result but allow players to intervene before it takes effect

@pliskavica @JeremyECrawford Example: assassin leaps from shadows to attack – he hits, use bend luck to turn it into a miss, then resolve

@JeremyECrawford why was the Delay, mechanic not only left out of the PHB but not offered as an optional in the DMG? #SageAdvice #dnd5e

We left it out on purpose. I'll delve into why in a future Sage Advice. https://t.co/455TWWSvbh

@ChrisPerkinsDnD 12 year old son wants to play a dwarf cleric of light. Recommended deity for his character?

There's Muamman Duathal, dwarven god of lightning & wanderers. He wields a glowing mace. Or Tharmekhûl, a fire god. https://t.co/mcepCRy8tp

@RodneyWade2Does this mean that every 8 hrs you automatically complete a long rest if you have spent less than 1hr of that time fighting? combat or other strenuous activity – travel, any work, etc. IIRC, you can get the benefits of a long rest only once per day.

— Mike Mearls (@mikemearls) June 18, 2015

@RodneyWade2Thanks! How much of that 8hrs do you have to spend asleep? 6hrs? (ignoring elf trance) PHB says no more than 2hrs light activity 6 hours seems fair
