Volt Engine

The final competitor stepped up to his platform, placing a hand on the inscription-sealed tarp covering his construct. The containment runes pulsed once before dissolving, the fabric disappearing into nothingness, a neat trick in which the mana bonds broke the thin tarp into microscopic pieces before turning them to dust with the overcharged lightning running through the material.

A metallic framework, sleek and polished, sat at the center of the platform. Unlike previous constructs, which bore visible inscription arrays, this one had no external runes, no obvious mana conduits, nothing that betrayed what its function was meant to be at a glance. Its frame was composed of three interlocking rings, hovering independently of each other, spinning at irregular intervals, their motion both deliberate and chaotic at once. The core, suspended in the center, was a sphere of shifting liquid lightning, its surface moving as though alive.
