@VNarvekMM says Elves are immune to Ghoul paralysis. PHB says adv. vs charm, no magical sleep. No change in errata. Immunity or no? Both books are correct in this regard.

My PHB just fell out, can it be replaced?
@ChrisPerkinsDnD a while back you mentioned an issue with book bindings. The races section of my PH just fell out. Can it be replaced? http://wizards.custhelp.com/

Monster Slam errata
@JeremyECrawford If an otyugh slams a creature and it fails its STR save it is stunned, stunned creatures automatically fail STR saves
— Tinker-TDC (@TubaDanCross) December 30, 2015
Take a look at the recently released Monster Manual errata, which fixes this issue:

Water Elemental DC 14 Strenght
@JeremyECrawford @ChrisPerkinsDnD Water Elemental (pg 125 MM) last sentence reads "…make a DC 14 Strength and…" A DC 14 Strength what?
— Todd Clayton (@tclayton) January 4, 2016
It's a Strength check. The new printing of the MM reflects that fact, so we'll add it to the errata document. #DnD https://t.co/qL9ggKLxaP

The Warlock familiar has all Monster Manual stats?
@JeremyECrawford the Warlock familiar has all MM stats? (Imp/Quasit CR 1 Pseudodragon/Sprite CR 1/4) They attack with poison and all? #DnD5e
— Miguel A. Espinoza (@nahualrpg) August 28, 2015
Yes, the creatures listed in the warlock's Pact of the Chain feature have the stats in their stat blocks. https://t.co/HoahKiEG0i

DMG How do you calculate the offensive CR of an ability?
@manofmysteryrmthe DMG custom monster rules confuse me. How do you calculate the offensive CR of an ability like gelatinous cube’s engulf it's more art than science, but as a rule of thumb I'd halve any future damage that can be avoided with a check or save
— Mike Mearls (@mikemearls) August 11, 2015
@manofmysteryrm for something like the cube, its final CR quite likely owes more to playtesting than applying offensive and defensive CR
— Mike Mearls (@mikemearls) August 11, 2015
@manofmysteryrmwhat do you mean by future damage? Ongoing effects like the engulf, or future as in how you calculate damage now on?
damage I might take because of something a critter did, but on my turn I have the chance to act to avoid it

Sheep stat block
@JeremyECrawford Quick: Stat block for a sheep?? #AskingForAWildSorcererFriend
— Bill Cavalier (@dungeonbastard) July 9, 2015
You could use the goat's stat block. Drop Str. to 10 (change attack accordingly), and ditch Charge and Sure-Footed. https://t.co/01gbKej4Bu
— Jeremy Crawford (@JeremyECrawford) July 9, 2015
@dungeonbastardok, what about a sheep with a feather beard?
Having a feather beard is its own reward.
