How do you deal with something grabbing onto a flying creature? Does its speed become 0 and start to plummet?

The grappled condition reduces any speed you have to 0. If you have a flying speed, it's now 0, and you fall unless you're hovering. #DnD https://t.co/KUjxluCLbL

So if you are flying under the effects of the Fly spell and you become grappled you fall? (Presumably taking the grappler with you)

The flying rules specifically say that being held aloft by magic prevents you from falling if your speed is 0 or you're prone (PH, 191) #DnD https://t.co/hM4AEeGPvZ

Thanks for the clarification. I looked at the Fly spell, not the move rules. So this applies to Aarakocras or other winged flyers. No problem!
