@JeremyECrawford if I have 120ft movement speed, 2 actions and a cunning action. could I dash 3 times in a turn? if so how far could I move

Dash adds X to your movement on your turn, where X = your speed. If you have more than one action, you can take Dash more than once. #DnD https://t.co/ZafYHnbHhS

@AjH_007 Out of curiosity, how is your speed 120 feet?

— Jeremy Crawford (@JeremyECrawford) September 20, 2016

@JeremyECrawford it's an extremely homebrewed campaign. I have boots that double movement which put me from 60ft to 120ft.

@JeremyECrawford Opportunity Attacks: Only make melee attack roll or use special feats (ex: Great Weapon Master -5 to hit, +10 dam)?

— Sean Bonney (@seanbonney) August 14, 2016

Opportunity attacks benefit from features that affect melee attacks (not ones tied to the Attack action). #DnD https://t.co/9F9Fe7FjXk

@JeremyECrawford When bards get spells from other class lists, do both spell choices have to be from the same class list?

— Todd (@fmacanadaguy) June 26, 2016

Magical Secrets: the bard can choose spells from different classes. #DnD https://t.co/sLeMaBh1Pt

@JeremyECrawford @SageAdviceDnD Do items that boost spellcasting (e.g. rod of war mage) help with the Counterspell roll as well?

— MovemberCzech (@LowWisdomCzech) November 12, 2016

Wand of the war mage grants a bonus to your spell attack rolls. An ability check isn't an attack roll. #DnD https://t.co/AuQXTtctJ3

@JeremyECrawford Is it possible for Aaracokra to cast spells while in flight?

— Nick Phillips (@crateguy) August 7, 2016

Flying doesn't inhibit spellcasting, unless a game feature says otherwise. #DnD https://t.co/tSgDwQ4RIW

@fmacanadaguyRegarding Elemental Affinity on p102 of PHB, does the ability to gain resistance require a spell being cast? It does.

@JeremyECrawford Magic Missile: Do you roll the same d4 for all darts, or one d4 per dart?

— Marc Sharma (@LeMarcSharma) September 8, 2016

Magic missile. RAW: You roll 1 damage die (see "Damage Rolls," PH, 196). RAI: It doesn't matter; you choose. #DnD https://t.co/AYRRX2j3AP
