Extinction

Summary
Extinction is a Crypt weapon that can be crafted with the help of the Fusion Caster. It appears to look exactly like Just a Lid except with a blue color scheme instead. It could be due to the fact the Unstable Energies were fused with the lid to create this weapon.

Trivia

 * This is one of the only two "class items" that can be crafted by the Fusion Caster, other being TRU3 CHA0S.
