Buy OSRS Ancient crystal
Description
The Ancient crystal is a members-only item in Old School RuneScape. It is a crystal that holds magical energy. Players use it to build an obelisk in their player-owned house.
To build the obelisk, you need four ancient crystals, four marble blocks, and level 80 Construction. The obelisk goes in the Superior Garden of your house. Building it gives 250 Construction experience for each crystal used. The obelisk is a handy addition for any player working on their home.
In the game, this crystal is a rare drop from revenants in the Revenant Caves. All revenant types can drop it, from the low-level Revenant imp to the high-level Revenant dragon. The drop rate is very low, so getting one on your own can take a long time. Being skulled raises the drop rate, but the skull from a high-risk PvP world does not count.
The Ancient crystal is tradeable and noteable. It cannot be worn and does not stack. It weighs about 13.6 kg. Buying this item is a fast way to skip the long grind in the Revenant Caves and get right to building your obelisk.
