Bottomless Bog

Bottomless Bog in Final Fantasy V (GBA).

A geomancy skill that inflicts damage with the power of water.
—Description, Final Fantasy Tactics.

Bottomless Bog (そこなしぬま or 底なし沼, Sokonashinuma?, lit. Bottomless Swamp), also known as Bottomless Swamp, Sinkhole, or Quicksand, is a recurring Terrain ability in the series. Similar to the Quicksand ability, it often inflicts Instant Death to all enemies.


Final Fantasy IIIEdit

III Sinkhole is an ability used through the Terrain command while fighting on the Saronia swamps or in Doga's Cave (floor 1/b). It has a 40% hit rate and will inflict Instant Death to one enemy with a high backfire rate. This ability is exclusive to the NES version of the game.

Final Fantasy VEdit

V Bottomless Bog is an ability used through the Terrain command while fighting on Swampland tiles. It inflicts Instant Death on all enemies, fails against Heavy-types, and is unblockable.

Final Fantasy TacticsEdit

FFT 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.

A bog is a mire that accumulates peat, a deposit of dead plant material—often mosses, and in a majority of cases, sphagnum moss. It is one of the four main types of wetlands.

A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer.

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.
