Hello, I need to donate soe marble from my storage to complete a task, but can't see how I do this ?
Any advice please ?
Thanks: :confused:

if you have enough press the tick in quest box it does it for you its same as if it say pay such and such a resorce

Try to visit the provision house, you can change the stones into marble in there. marble produced from it will be stored in the star menu, then you can use it to complete your task.
hopefully can help you,
