^That is fucking CLEVER.

Reznor, we're gonna do an Appeal I'm calling 'The Lightning Gun.'

First, use Ice Beam to create the 'barrel' of the gun around you: Make a ring of ice for a sturdy base, then make a coil upwards around you, getting narrower as it goes up until the opening at the top is like half-size. Then fire a Sludge Bomb straight up in the air, out the 'barrel,' and end by detonating the Bomb with a Thunderbolt. Light up the sky!

Move: Ice Beam ('barrel'), Sludge Bomb (lightning 'seed'), Thunderbolt ('ammo')
