Cleaving was an Abyssea term used for pwning the ***out of multiple enemies at a time for exp/gil/<insert currency>. The term came from the WAR Great Axe Weaponskill "Fell Cleave" which, during the Abyssea era, a WAR and a WHM could basically duo an entire area of mobs (generally the same mobs, given the exp increases killing the same mobs over and over again) by having the WAR gather a *** of mobs together, running over to the WHM, WHM curebombs the ***out of the WAR while the WAR uses Retailiate and Fell Cleave when TP hits 100% (or 1000).
Fell Cleave owns the ***out of mobs due to it's AoE and high damage capabilities. With the right Atma, a WAR can essentially solo the area himself if a WHM is not present.
