@jhansonxi @JeremyECrawfordIs a monk’s Shadow Step a spell? Does it cancel Invisibility?
not a spell IIRC

@gaaran00bwhat do you do with a kill joy player? I have one who does nothing but complain about his bad rolls and calls himself useless
oh man, tough one. try talking about the problem. don't threaten, just say "hey, is what you do fair to the entire table?"

@JeremyECrawford Can a rogue use evasion if he is surprised? The rule states that "If you’re surprised, you can’t move or take an action…"

A surprised rogue can use Evasion, since that feature doesn't require the rogue to take an action or move somewhere. https://t.co/f43j2dcjrl

@toshle123ee @JeremyECrawfordHow would you create a 5e NPC? Instead of the monster stats, using player stats
i comp final stats to CR guid, simplify. For instance, champion fighter, pick 1 – 3 scaling spells for casters

@mikemearls @JeremyECrawford Shield master can take bonus action before an attack. Can a monk flurry before attack? Wording is different.

@Dr_Brehob @JeremyECrawford don't believe so

Flurry of Blows happens "immediately after you take the Attack action on your turn" (PH, 78). https://t.co/va0p1agI3R

@JeremyECrawford Is stepping off a wall into a drop of 10 feet or more acrobatics or athletics? Or would you say you can use both.

— Steven Connor (@Mazoshi1987) August 5, 2015

I've allowed characters to use either. It depends on the circumstances and the player's description. https://t.co/4wkU3HfFfl

@AtomicDekeCan a willing shapechanger (i.e. a changeling) be affected by Polymorph, or does the auto-success saving throw come into play?
i'd let a shapechanger forgo the save – but remember that polymorph does change mental stats, so I'd rule NPCs opt to save

@JeremyECrawford @mikemearls If I move directly through a medium creature's space, does this cost 15ft or 20ft of movement?

— Dominic Dalton (@djddalton) August 5, 2015

It costs 15 ft. of movement when you do that. https://t.co/XH8RZmMYg4
