@JeremyECrawford What if I'm dual-wielding a dagger and a whip, can I use the dagger when someone leaves my 5' but stays w/in 10'?

If you want to make an opportunity attack with X, the attack is triggered when a foe leaves the reach of X. X = weapon you want to use #DnD https://t.co/MUcJpn4Vvr

@JeremyECrawford Awesome! So does that mean you can always make a 5ft unarmed Opportunity Attack, IE if holding a two handed weapon?

Unless a feature tells you otherwise, you have a 5 ft. reach with your unarmed strikes, and you can make opportunity attacks with them. #DnD https://t.co/ezYaayMNuo
