I know you might think sell wands are a little op, but with these huge farms that are popping up they would be very useful in selling large quantities of things. For instance, I want to make a much bigger melon farm but i dont want to go through all the moving the melon into my inventory.
This was already something that players requested and it was already added (sell shards). You can buy them here.
As @Chickencharm mentioned, Sell Shards are an improved version of the Sell Wands. While it's not an entirely accessible item as of now, we plan to make it more available in the future. Thanks for the suggestion anyways!
