A geomancy skill that inflicts damage with the power of water.
Quicksand (底なし沼, Sokonashi Numa?) is a recurring ability in the series. It is often used by enemies, but is also an ability the party may use, usually used with the Geomancer class. It either removes a target from the battle or inflicts non-elemental damage to the entire party.
Quicksand is used by the boss Sandworm and by the enemies Desert Killer and Spizzner. It inflicts 60 fixed non-elemental damage to the party and inflicts Sap. It is also a Gaia ability which can only be used when fighting in deserts, and inflicts instant KO to all enemies in the battle.
Quicksand is a skill that can be learned by the Geomancer job. A Geomancer standing on either the Marsh, Swamp, or Poisonous Fen terrain tile will use Quicksand to deal Water-elemental damage with a chance of inflicting Doom to any enemy units within five squares. It costs 150 JP to learn.
Quicksand is a colloid hydrogel consisting of fine granular material (such as sand or silt), clay, and water formed in saturated loose sand when the sand is suddenly agitated. When water in the sand cannot escape it creates a liquefied soil that cannot support weight. Quicksand can form in standing or upwards flowing water. The saturated sediment may appear solid until a change in pressure or shock initiates liquefaction causing the sand to form a suspension and lose strength. Objects in liquefied sand sink to the level at which the weight of the object is equal to the weight of the displaced soil/water mix and the submerged object floats due to its buoyancy. Liquefaction is a special case of quicksand where an earthquake increases the pore pressure of shallow groundwater. The saturated liquefied soil loses strength, causing buildings or other objects on that surface to sink.
