@SalmonSquireWhile you can incapacitate creatures to harvest their poison, can you comman a ranger’s snake to put poison in a vial?
i'd say no

@SalmonSquireThank God. A player was going coat all his weapons in giant poisonous snake venom. 3d6 damage. I got your back, fellow DM!

Other @JeremyECrawford tips: the flexibility of monster hit dice helps DMs tweak difficulty easily. Dial up or down to suit. #dnd

Social combat in #dnd5e – what is your solution to PCs wanting to influence PCs? @ChrisPerkinsDnD @DMs_Block

— Swordnut Radio (@SwordnutRadio) July 5, 2015

Unless charm magic is involved, a player has full reign to let his or her character be influenced or not. IMO. https://t.co/UvepgkSIrm

@NontoxicGamer @JeremyECrawfordWild Magic Table – lightning bolt effect says “up to three.” Can the sorcerer choose to target fewer than 3?
yes

@Kynewulf74 @JeremyECrawfordHow would pole vaulting work in 5e? Converted Thief-Acrobats want to know. 😉 I'd say it allows you to complete a vertical jump equal to your Strength score

— Mike Mearls (@mikemearls) August 7, 2015

@Kynewulf74 @JeremyECrawfordSo the length of the pole wouldn’t matter or impact the jump?

(That could probably have been better worded.) the length falls into a kind of narrow band, IIRC. To short, doesn't help. Too long breaks. I'd use RL measures

@rhouckdnd @JeremyECrawfordcan druid wild shape from form to form? (eg,druid is bear, can he change direct to snake?) or only extend bear?
yes

— Mike Mearls (@mikemearls) August 6, 2015

@rhouckdnd @JeremyECrawford however, each change requires a use of the ability, save for returning to your true form

Another @JeremyECrawford tip: pay special attention to the multiplier in encounter building. They know it’s hard but it’s the REAL DEAL #dnd
