I don't wan't to add this item because it looks too overpowered for what it does. I think it would be better if it was only one coin, or instead a rare item (to be honest very rare wouldn't be unfair in my opinion, giving 2 more coind to that many units is very strong)

Sure, this is the script. Instead of using "value_bonus" you would use "value_multiplier" after "value_to_change".

Hey! Think you could teach me how to make an item that doubles specific symbols? The best I could do was make an item that gives coins based on the numbers of a specific symbol. Thanks!
