@konafusiona 20th lvl fighter with haste and 2-W fighting can make 6 attacks per round, right? Then action surge for 1 or 4 more? Yes, and Action Surge does let a fighter use Extra Attack again.

@JeremyECrawford What about the additional action from a Haste spell? If used to attack, does extra attack get added to it as well?

— Ambryn (@konafusion) February 5, 2016

The haste spell states that you can make only one weapon attack with the action it provides. #DnD https://t.co/tR7JKfpvYa

@JeremyECrawford Player has Lunging Attack and Sentinel. Monster moves around Player in a 10ft radius during Player's Turn. Do AOO happens?

— Stefano (@elerital) February 17, 2016

The fighter's Lunging Attack increases the reach of a single attack. #DnD https://t.co/2NZy5zNRvG

— Jeremy Crawford (@JeremyECrawford) February 18, 2016

@Daeva001 In other words, the trigger for the OA never happens, since you can’t increase your reach until you’re already attacking. Exactly.

— Jeremy Crawford (@JeremyECrawford) February 18, 2016

@JeremyECrawford @Daeva001 In other words: PHB 195 if lunging attack is exception to attack range rules why not to AOO, Isn't AOO an attack?

— Stefano (@elerital) February 18, 2016

Lunging Attack increases your reach the instant you use it; it doesn't give you an always-on extended reach. #DnD https://t.co/kgdw6LZcMe

@JeremyECrawford When the Sorcerers use the meta magic Subtle Spell can you avoid being effected by counterspell if no materials are needed?

— Michael Freeman (@mykesfree) February 2, 2016

Counterspell requires you to see a creature casting a spell. Nothing to perceive means no counter. #DnD https://t.co/EWAaA5N2dL

— Jeremy Crawford (@JeremyECrawford) February 3, 2016

@MerricB Doesn’t casting a spell with a longer casting time require concentration? The reference on PHB 202 even mentions rituals. That's correct!

@mikemearls @JeremyECrawford Would a mountain dwarf druid trained in dwarven armor use metal armor?

— Leonardo Raele (@LeonardoRaele) February 15, 2016

Druids of any race abide by the taboo against wearing metal armor. #DnD https://t.co/0S9WjcmlDB

— Jeremy Crawford (@JeremyECrawford) February 18, 2016

@JeremyECrawford Druid Fighter multiclass still no metal armor?

— Carmine (@nirvanstryder) February 18, 2016

The druid taboo against metal armor isn't erased by the multiclassing rules. #DnD https://t.co/FjQEsMYkhf

— Jeremy Crawford (@JeremyECrawford) February 18, 2016

@jaa0109 @nirvanstryderWhat if it were leather armor with spikes and flames?

Could it be Metal then? That would definitely be heavy metal!

— Jeremy Crawford (@JeremyECrawford) February 18, 2016

@JeremyECrawford Can a spell like Macimillians Earthen Grasp or Telekinesis which targets 1 creature but u can change to another be Twinned

— Carmine (@nirvanstryder) February 2, 2016

Can a spell at its current level target more than one creature? If yes, you can't twin it. #DnD https://t.co/zDJSO5oUtx

— Jeremy Crawford (@JeremyECrawford) February 3, 2016

@JeremyECrawford @nirvanstryder that seems vague still to me. At casting, earthen grasp can only target one, but can be moved later…

— eric moss (@eerongal) February 4, 2016

A spell like Maximilian's earthen grasp doesn't target anyone at first. You create a thing, which then targets. #DnD https://t.co/meeJsGJlkO

@JeremyECrawford Can you ready an action to trigger after the first ray of series of Eldritch Blasts? Can EB be the target of Dispel Magic?

— Iva Novak (@mellephone) February 5, 2016

A spell with an instantaneous duration can't be dispelled (PH, 203). #DnD https://t.co/rg9cPs2SuB

@yr43lHey, if a caster polymorphs himself, and then takes damage in the polymorphed form, does he need a concentration check? Yes.
