Divination skill allows you to create divine places. It is possible to gain a lot of resources in a short time, so be sure to hit the daily limit. These locations have a high XP/time, GP/time ratios and are worthwhile. The daily limit you can set is based on RuneScape Mobile gold your overall level. It can be 250 at 2500 or 250 at the maximum. Each resource you harvest and every noted resource received from others using your location of divine will count toward the limit you have set, but some resources filling up your limit faster than others.
You can create as many divine locations as you like per day, but can only create one per day. If you want XP then you must get it from holy locations that others have put up. You aren't able to create your own. If you're not concerned about XP and simply want to earn fast cash, then you must put divine locations you like in areas that are crowded.
World 48 Burthorpe is the best place for Divine Locations. It's open at the hour of 0:00 UTC. To find out the time you need to use alt+ to buy OSRS gold open the developer's console and then type whatever you want to type. World 2 Burthorpe is an alternative if World 48 isn't accessible.
