UA Ranger – Spirit Guardian
@jtburlingUA Ranger: Spirit Guardian benefits at higher lvls, 7,11, etc – are they powered by the same single “use” as the lvl 3 ones? yes, though not all of them will require it and this ranger would gain more uses at higher levels

Wild Shape to Wild Shape
@aloadofbullshitCould a Druid already in beast form use wild shape to switch to another beast? Would they need to revert first?
can change from animal to animal

@aloadofbullshit so you can change into a bear with full hp when you get to 1hp in panther form? Can you also change from a bear to ‘new’ bear?
Yes, as far as I recall

Could a PC have blindsight?
@IvanCortez_ @SageAdviceDnD I'd allow it, but it's a powerful ability. would consider treating it as normal sight with a limited range
— Mike Mearls (@mikemearls) August 31, 2015
How far would you allow? 30ft? 50? https://t.co/6U8FEgNVDU

@IvanCortez_ @SageAdviceDnD 30

Mariner Fighting Style
@gaaran00bwhat classes are allowed the Mariner FS? Could I give it to a Swashbuckler? it's for any character with access to the FS feature. For the swashbuckler, maybe replace one of its higher level abilities

Bag of Dungeon Master
@JacobonautHey @mikemearls / @JeremyECrawford – what kind of bag do youse guys use to lug your D&D books around in? Mine’s becoming worn.
I usually DM at home and play at work; the books are there. When I DM elsewhere, I carry my books in a suitcase. @mikemearls

@Jacobonaut @JeremyECrawford I use an iPad-sized Rick Steves satchel. I typically leave rule books at home – write monster stats on cards

Can Haste extra action be used to activate a magic item?
@JeremyECrawford can the extra action granted by Haste be used to activate a magic item?
— Alvin Ty Law (@alvintylaw) August 25, 2015
No. Activating a magic item isn't a function of the Use an Object action (DMG, 141). https://t.co/PuGBkS3yfm
