Darkfog is a spell used to confuse the enemy by emitting a stream of dark fog. This can be done to obscure an opponent's vision for an unseen attack or an emergency escape.
History
Lok Lambert used Darkfog to obscure Rassimov's vision of the Casterwill Compound's gate, in Atlantis, allowing Lok to invoke Lindorm and attack an unsuspecting Rassimov. The spell Hexkill was used by Rassimov to counter Lok's spell, but it was too late. S1E21
On the Huntik team's way to the Golden Asp, Darkfog was cast by Zhalia Moon to prevent two Organization Suits who were following them from seeing Lok Lambert's Bristlebind spell, making their car bump into the vines and flip multiple times. S1E22
At the roof of Dante Vale's house, Lok Lambert used this spell again to obscure Simon Judeau's vision while trying to sneak up on him. However, Simon was still able to grab Lok through the spell. S1E24
During the final battle against the Professor, Lok Lambert momentarily blocked Tao's vision with Darkfog, allowing Gar-Ghoul and Ariel to attack it. The spell later dissipated, letting the Legendary Titan sweep off Gar-Ghoul and send a faraway Ignatius back to its amulet. S1E26
In the coast of Northern England, Lok Lambert used this spell to cover up the Huntik team's exit into the cliffs from the beach when they were attacked by three Organization Suits. S2E30
Tantras cast Darkfog at the Erasmus Bridge to allow him and his recruits to escape after the battle for Vigilante's amulet turned the Huntik team's way. S2E33
Darkfog was once again used by Tantras to retreat with his new students after noticing Powerbonded Lindorm in the streets of Venice, Italy. S2E36
Dante Vale cast this spell when fighting Wind hand-to-hand to obscure his vision and help a troubled Lok Lambert and Sophie Casterwill inside the Phoenix Volcano. However, Wind reacted quickly and knocked down Dante with a spell of his own through Darkfog. S2E45
Darkfog was cast by Harrison Fears to sneakily take out a group of Organization personnel at the entrance of the Tomb of Tutankhamun. S2E47
