Can anyone say what a stack of sponges cost or should cost? i have extras i would like to sell if they have any value,
You can get an average of 30ish sponges per ocean monument, more if your lucky. Its not all that hard to find unraided monuments with elytra and rockets, lets say an hour per monument, and then it takes 20-30min to clear a monument solo, I'm being generous with these estimates, how much would you value an hour and 30min. of your time?
You could call it 1-2 diamonds per sponge, but the final price is up to you.
Also if your selling a stack of sponges let me know, depending on your selling price I may be interested.
