Cosmic Rift!

'Cosmic Rift?' Felix raised an eyebrow in intrigue.

'It's one of the divine axe's strongest attacks.' Elder Cyclope said, 'Just make sure to channel spatial elemental energy to activate it.'

'Alright.'

Felix didn't ask for more as he wanted to see the attack with his own eyes. The first thing he did was increase his size with the axe yet again to a celestial height.

'I am going to show you that no one else is capable of wielding you as good as me in this entire universe.' Felix uttered indifferently as he eyed the divine axe.

Then, he began channeling the spatial elemental energy into it, causing a portion of divine inscriptions to light up, responding to the call.

As he drew on the fathomless depths of his power, the axe responded in kind; its edge flaring with hues unseen, as if drinking in the very essence of the cosmos.
