Fissure and King Fissure are abilities in the Dragon Quest series. Both skills attempt to open up a chasm to send enemies to their doom. It must be noted that the animations for both skills show a sucking vortex pulling enemies into the gorge, which explains why the skills is effective against flying foes.
Fissure is learned by advancing to Rank 5 of the Sage vocation. The skill is a free version of Kathwack, utilizing the same resistance table. It is useful for players that prefer to conserve MP, but there is a 33% chance for the skill to fail regardless of its target's vulnerability, and cannot be used while at sea.
In the original PSX version, fissure can only be learned by reaching rank 4 of the Golem vocation, and it possesses the same aspects as in VI.
As implied by its name, King Fissure is a superior skill to the original. Though it costs 15 MP to use, it affects all enemies and is not influenced by the terrain nor fizzle and bounce, making it more reliable than Kathwack
