Corundum is one of the Jewels of the Elid found in Menaphos. It can be obtained from mining corrupted crystals or looting chests in the Shifting Tombs, with a 1/750 drop rate. Collecting all 16 gems grants the Jewelled Scarab pet.
- Corundum in real life is a mineral that can come in a variety of different colours; red varieties are called rubies and blue varieties are called sapphires.
- Corundum was formerly known as Tuai Leit sparkle, introduced to the game on 10 October 2016, but was unused. It was re-purposed and renamed with the release of Menaphos.
