Guild Wars 2

Im new to the dungeon system and needed some clarification.

I ran the Twilight Arbor for the daily bonus today. I received 20 blooms
in end chest plus 40 for bonus.

The second run I received 20 in chest only, which I expected. The third run
was only 10 from chest.

Does this diminish down to 0 on any more runs during same day?

Not 100% sure how it works, but I believe it goes down to 2 tokens as a minimum.

I don’t think anyone runs dungeons more than once a day anymore except to sell them.

Ah ok, thanks for the reply.

It’s been ages since I repeated the same dungeon on the same day, but did you switch characters or did you keep the same one ?

I don’t remember if the number of tokens drop down whether you switch character or not.
