@bjrollet @mikemearlsI have yet to see a spell desc that states material comp are consumed. are they always consumed upon casting? Material components aren't consumed unless a spell, such as raise dead, says so.

@bjrollet @mikemearlsawesome! so you keep your pearl when you Identify… That's right! The identify spell doesn't consume the pearl.

@IHitItWithMyAxeHI Jeremy? Does uncanny dodge work automatically on every seen attack the rogue gets hit with? Magic too? Yep! Uncanny Dodge works against attacks of all sorts, even spell attacks.

@nirvanstryder @IHitItWithMyAxedoes it work against each successful attack made by opponent who has multiple attacks or is it one attack A use of Uncanny Dodge works against one attack. Like Defensive Duelist, it expends your reaction.

@BrailSaysMechanically,any diff between spell “permanent” and “until dispelled”? Mordankis Private Sanctum dispellable? "Mordenkainen’s Private Sanctum dispellable?" Yes.

@JeremyECrawford Does Dawn cylinder go through walls and floors? Asking for a friend.

The area of effect of a spell, such as the dawn spell, doesn't extend through total cover, like a wall or floor, unless the spell's description says otherwise.

For more on how areas of effect work, take a look at "Areas of Effect" in the PLAYER'S HANDBOOK (p. 204). #DnD https://t.co/KUpypaWAAW

@BrailSaysDruid/Monk,unarmored defense usable in shapeshift forms? The druid/monk could use Unarmored Defense or the beast's AC calculation. @mikemearls

@pizzystrizzyQuestion about Thunderwave — can it affect all adjacent squares by casting from, say, the bottom of the cube (from the inside)? The origin of a cube must be on a face of the cube. Cast upward, thunderwave could affect Large or larger targets next to you.

Twin and War Caster have always been different enough to have unique rulings. Twinned Spell requires the spell to be incapable of targeting more than one creature. For War Caster, it doesn't matter how many creatures the spell CAN target, only that it IS only targeting ONE.

Twinned Spell and War Caster in D&D both care about number of targets. But their descriptions define that concern in different ways, and they intentionally play differently. @DMdandanfieldng describes perfectly below how the difference in wording creates different effects. #DnD https://t.co/HWX3rfdnAs

@atkinsonnathanj Archery fighting style only affects weapons under ranged cat. on p149 phb, not weapons with the thrown property? This RAW?
That’s correct. A melee weapon with the thrown property is still a melee weapon when you throw it.
