A Stone slab is mined in the TzHaar City mines, in the southeastern part of the city. Level 41 Mining is required, and 40 mining experience is received when mined. It is possible to get gems while mining on obsidian walls. It is recommended to bring a high-end pickaxe for mining. It is not possible to mine stone slabs with a Gilded rune pickaxe, Sacred clay pickaxe, or pickaxes made of adamant and below, including the Dwarven Army Axe.
If you use a chisel on this with a hammer in your inventory, you get 20 crafting experience and a pillar. It is used in the TokTz-Ket-Dill quest. 5 stone slabs are also required to build a Volcanic habitat in a Menagerie in a Player-owned house using the Construction skill at level 77.
As these stones are said to be obsidian, the slabs can neither be smelted or smithed to make items.
Accessible only after getting permission during the TokTz-Ket-Dill quest, this mine is located through the passage in the northeast corner of TzHaar past the TokTz-Ket-Dill Mine. Each vein can be mined twice before it is empty. There are 16 veins from which stone slabs may be mined with a fast respawn time. The nearest bank is the TzHaar city bank.
- It takes roughly 30 seconds to deplete ones run energy from 100 to 0 while carrying a full inventory of stone slabs.
