On this page you will find information about Gambling in Diablo Immortal. It will allow you to obtain new items for gold. Find out about the rules and in-game restrictions for this activity here.
In Westmarch, you will find Rarities and Antiquities shop. Here you can spend gold to get an item of a certain type. The daily limit is 25 items of a given type, but after purchasing 10 items of one category, the price of the next ones increases by 150%. However, the limit is reset the next day.
Gambling allows you to get legendary items, but you have a very low chance for that. It is worth coming in every day and trying your luck by spending excess gold to get rare items. You can use legendary items or extract essence from them - the rest of the items can be salvaged and use in strengthening your gear.
