Bird up

What happens to the token after it's used? I assume by the consumable tag that it disappears completely after its use?

That's my reading as well. On the Feather Token base page it's referred to as single use.

That said, I'm letting my party use it on as long rest. It's a more interesting magic carpet!

I agree. Bye bye Aladin!

How could you nerf this for combat? I'm nervous about my players using this for cheesy combat...

The item description already answers that for you. "The bird has the statistics of a roc, but it obeys your simple commands and can't attack." So it is only intended for travel. You don't have to worry about your players using it to fight if you decide to offer it to them.

I definitely misunderstood this item at first and let my party use it once per day. It honestly became rather balanced given the scope of the adventure. (Traveling across whole continents.) Samara was the name they gave the Roc and she became an invaluable member of the party used for verticality in combat, long distance travel, and hauling large items. For high level play this item adds a ton of versatility whether its used Raw or rule of cool.

So to clarify, if the roc doesn't fly its maximum distance in a single day (say you have it fly 60 miles a day), does it last for longer? If you ride on the roc for 60 miles a day, will it vanish on the third day, or will it stay around?

I will say that it's carrying capacity is weirdly low... Like, a normal roc can carry a little over 3000 lbs but whatever.
