Blade of eternal hell

Name- Hast
Power- Being made of a material of plasma, which is the material used to make up stars and other powerful substences, mixed with concentrated diamond to contain it appropriately, the blade is able to cutt through virtually anything, though if the material had the same durability as the user's energy, they would be able to withstand the blade's power. It is can only be made by using physical matter and mixing it with a near-by heat source like fire to create a diamond coated plasma blade. The plasma emits heat upon contact with the diamond, but unless contact is made, no heat can be felt from the blade. This is due to the complex make up that can only be done due to Zane's high mastery in his alchemic power.
