If a dragon loses a limb in battle & then runs away because it doesn't want to die, can it regrow the limb?

— Mathew Michalak (@Trogaf) June 8, 2016

Only if it has some magical means of regeneration. https://t.co/caNwBp7w46

@JeremyECrawford Creature w/ Immunity to Fire is hit by Contagion spell & becomes "vulnerable to all damage." Is it now vulnerable to fire?

— Ed Robinson (@Lwnasidh) June 16, 2016

If a creature is immune to a damage type, making the creature vulnerable to that type does nothing (2 x 0 = 0). #DnD https://t.co/GV926kIYIu

@JeremyECrawford tweet is better without the shorthand since you could also argue base % -100% + 100% = base%

— Justin Melillo (@Cybren) June 16, 2016

Vulnerability is applied after all other modifiers to damage (see PH, 197): 0 damage passed to vuln. stays 0. #DnD https://t.co/K4yOfEMzpe

@Cybrenright but my point is people that already know that aren’t asking you! Indeed. Hence my response.

Hey @ChrisPerkinsDnD, do werewolves have an aversion to silver outside of their beast or hybrid forms?

— Ethan Bohr (@EthanBohr) June 8, 2016

A werewolf's damage immunities apply to all of its forms, including its human form. https://t.co/MulS1xNrU8

@kevinsingholee @ChrisPerkinsDnDwhat are the penalties for a character who uses a weapon they are not proficient with in 5e? No penalties, but they cannot add their Proficiency bonus to any attacks with it

@RatofDrawnSorry for the question, google was no help. If Ranger rolls crit /w Hail of Thorns on, does he roll double damage for that too? yes

@JeremyECrawford Can you use the healer's kit to stabilize a PC at 0 HP if you don't have the Medicine skill prof? Maybe requires WIS check?

— Robin H. Wilde (@RMHWilde) May 31, 2016

A healer's kit can be used by someone without proficiency in Medicine. #DnD https://t.co/MHlNzM2ksS
