The Kurse Stone was a mystical stone used by elite Dark Elves to improve their physical capabilities at the cost of certain death some time after the transformation.
During their final battle against Asgard, some of the Dark Elven warriors used these stones to become Kursed, growing in height, size and gaining massive increases in physical strength and durability. For a short time, these "super soldiers" overwhelmed Asgard's forces, though they were eventually overwhelmed by the Asgardians' superior numbers.
- Kursed Transformation: Dark Elves naturally possess superhuman strength. By crushing the Kurse Stone in their hand, the Dark Elf's clothes and armor merge with their skin, they grow in size and their physical strength and durability increase massively. The Dark Elf also gains the ability to burn those they touch with their "curse" at will.
