The Dark Potion can be drank by Miners as of now. Only one potion can be active at a time and it still doesn't stack as usual (DO NOT drink it twice while your timer is still running!).

While the dark potion is active, any diamonds mined by miners will become Dark Diamond.

To give the potion to the Miners, you need level 100 Mining. (This is assumed to be the same for Farming and Woodcutting, this needs verification when the option has been implemented.)

Bugs Edit

The Dark Potion description says it is brewable from level 70, but when you click it, it says it is craftable from level 75.
