Juju mining potion

A Juju mining potion is a reward from the Herblore Habitat activity. It requires 74 herblore to make. When a dose is consumed, each ore mined has a 10% chance of finding a stone spirit.

Once found, the stone spirit will send all ores mined directly to the bank for 30 seconds, including extra ores obtained with the Varrock armour and bonus ores gathered from concentrated coal and gold rocks. The potion also gives a small chance of receiving higher level ore (also sent directly to your bank). Each dose of potion lasts for five minutes. A message will warn you one minute before the timer runs out. More than one spirit may be acquired during the five minutes after each dose.

Making this potion grants 168 herblore experience and requires a clean samaden and a draconic vine.

The stone spirit will not appear while mining granite, clay, sandstone, rune essence, pure essence or gem rocks. The message "The stone spirit magics your ore straight to the bank" is displayed whenever ores are banked.

The effect of the potion will be lost whenever logging out or disconnecting. If the 5 minute timer runs out while you still have a stone spirit active, the stone spirit will still remain for the full 30 seconds.
