Indestrunite

Indestrunite
Indestrunite is a mineral discovered by Brodrej on the North Pole and is the hardest and most durable material in existance. It is known to be almost entierly indestructible. Zephyria did at one time shatter indestrunite without another indestrunite-based method, but that is the only known scenario.

Indestrunite has different purity and is divided into 5 tiers (5 being pure indestrunite).
