Druidic Ritual (historical)

The Stone Circle
Speak to Kaqemeex in the stone circle north of Taverly and he will tell you that the stone circle south of Varrock used to belong to them but was taken over by the Dark wizards. He then tells you that you must speak to Stanfew.

Stanfew
Speak to Stanfew, located upstairs in the big Herb shop marked with an Herb, and tell him that Kaqemeex sent you. He will then tell you that he needs you to place Raw rat meat, Raw bear meat, Raw beef and Raw chicken placed in the Cauldron of Thunder.

Enchanting the Meat
The Cauldron of Thunder is located in Taverly Dungeon. If you are a lower level, it is advised you bring food with you for the next part. Head south of Taverly and down the ladder. When you are down there, keep walking north, past the Skeletons until you see two suits of armour on stands next to a gate. Note: When you attempt to open the gate, one will attack you. It's combat level is 19. Kill it and walk in. You will now see a Cauldron. User the Raw Meats in your inventory on the Cauldron of Thunder and you will notice they will turn Blue. Also, instead of Raw rat meat, for example, it will say enchanted rat or enchanted bear.

Going back
Leave the dungeon the same way you entered and speak to Stanfew. He will take the meats and tell you to speak to Kaqemeex.

Kaqemeex will tell you about the skill of Herblore.
