Lightning Dragon's Heavenward Halberd

is a Lightning Dragon Slayer Magic Spell.

Description
The caster raises their hands and forms lightning between them, forming a very large spear out of it. They then hurl such spear at the enemy. According to Freed Justine, this spell is strong enough to kill a weakened Natsu Dragneel if it hadn't been redirected at the last second by Gajeel Redfox.

Trivia

 * The weapon resembles a traditional Chinese Ji in appearance.
