Can u counterspell a magical triggered trap, or if sets off something like stone wall(spell) can it be used on 1part/all. @JeremyECrawford

Counterspell says in its Casting Time entry that you cast it in response to a creature casting a spell. A trap isn't a creature. #DnD https://t.co/eDtALVpfwz

@JeremyECrawford How does 1 kill a vampire that's been forced (@ 0hp) into mistform? Is it only by following it and staking it & THEN kill?

— Evhelm (@Evhelm) April 11, 2017

The capabilities of a vampire's mist form are specified in the monster's Shapechanger trait. #DnD https://t.co/iqiPrpGv7B

@JeremyECrawford Does the bonus atk given by Crossbow Expert require the first attack to hit?

— Bernardo Henz (@bernardohenz) April 3, 2017

The bonus attack in Crossbow Expert is not contingent on the other attack hitting. If it were, the feat would say so. #DnD https://t.co/DSUVyfPAyu

@ChrisPerkinsDnD does a thrown character take fall damage for ft above 10 or do you make an acrobatics check to see if they do(/fall prone)?

— Mathew Michalak (@Trogaf) March 19, 2017

If you fall 10 feet or more, you take damage, unless an effect or the DM says otherwise. #DnD https://t.co/41L37NK6kD

@JeremyECrawford the escape saving throw to avoid vampire's grab is based on strenght or dex?

— Exo (@PilgrimTim) March 25, 2017

"Grapple Rules for Monsters" (MM, 11) explains how you escape from a monster's grapple. #DnD https://t.co/vC2UKERmsV

@JeremyECrawford When the shapechange spell says you don't get Spellcasting, does that include Innate Spellcasting?

— Staffan Johansson (@DackeStaffan) March 25, 2017

Spellcasting and Innate Spellcasting are two different traits. #propernouns #DnD https://t.co/hcEihmUDno

A round can be measured in different ways: e.g., from the 1st initiative to the last or from the start of your turn to your next one. #DnD https://t.co/XstRorhbl6
