Seren stone

Seren Stones are crystalline rocks that require 89 Mining to mine from. They will be found in the Hefin area of Prifddinas, surrounding Seren Crystals. Each Stone can be mined 70 times before it goes through a trapdoor. No ore will be produced from these stones, making them similar to choking ivy, but they will give the highest rates of Mining experience in the game.
