@JeremyECrawford In my turn if I have Extra Attack, does Injury Poison (with CON ST) work for only ONE hit or for EACH hit of Extra Attack?

Injury poison is spent when a creature takes the piercing/slashing damage that delivers the poison (DMG, 257). #DnD https://t.co/xjyDtQNhhC

@JeremyECrawford Thanks! But Poison Basic PHB p153 which rule follow? Is like injury poison or not?(it said only remain potent for 1 minute)

— Draconis (@DerynDraconis) April 19, 2016

Basic poison (PH, 153) is potent for 1 minute after it's applied. As written, it works on multiple hits. #DnD https://t.co/AeVC1W3j1t

@JeremyECrawford @DerynDraconis
Are drow poisoned weapons from Monster manual treated the same way?

A monster stat block tells you if an ability in it has a limited number of uses or a duration. #DnD https://t.co/g4WUoddv2j
