The {Elemental Vault} was a very peculiar skill. It's existence itself qas simply happenstance and a decent sprinkling of luck. However, there was also a mystical aspect to it as well.
Electricity spazzed through the chains on his hand. Cain concentrated as he activated {Heavenly Blue Lightning}. A magic circle appeared above the chains, and a bolt of lightning struck down. Cain could normally conjure a very scary amount of lightning. However, the density of the lightning mana he had gotten from that torturous experience wasn't that great.
However, it was more than enough to destroy the chains. The chains fell towards the ground. However, they stopped just as they were about to hit the ground.
Cain's eyes shone with a golden luster as he gently lowered the chains to the ground so as not to make any unnecessary sounds.
Then he walked to the iron bars that made up the gate of the prison cell.
