Is there cooldown between fishing Shimmer Swimmers?

Question

I know we can only get 1 Shimmer Swimmer per Server Save.

But is there a cooldown between 2 fishes? For an example, if I get a shimmer 10 minutes before Server Save, can I get another right after Server Save? Assuming World Change will still be active?

Or do I have to wait some times, like a 20h cooldown, or something similar?

Answer 1

You need to wait. Acoording to brazilian Tibia Wiki you have to wait 20 hours to get another fish after you get one.
