@JeremyECrawford If a 14th level Ranger casts Lightning Arrow as a 4th level spell, how many arrows that round are transformed?

— Jaden Stormtracker (@jstormtracker1) September 7, 2016

Lightning arrow transforms 1 piece of ammunition or 1 thrown weapon. #DnD https://t.co/rwkrfI3vbp

Unconscious says u fall prone. Does this mean all the conditions of Prone apply? Would attacks 5ft> be adv+disadv=neither?

The prone condition applies to you whenever you're prone. #DnD https://t.co/n05h7brcnj

@SwedishGamePros @mikemearlsIf you cast Aid at 3rd level, do all targets get 10 HP or just one? “each target” vs. “a target” confusing me. All the targets

On the partnership of mage armor and a shield, see the Sage Advice Compendium: https://t.co/dh02JRnEH8 #DnD https://t.co/Y0oNoavc7X

@Gutzindaffer @mikemearlsGnome Artificer’s Lore – Does the wording mean you have to have proficiency in order to get the double prof? A gnome doesn't need proficiency in History to benefit from that trait.
