Final Fantasy elements

The following is a list of elements in Final Fantasy. In the original Famicon and NES releases, spells and attacks can have 8 elemental and status properties: Fire, Ice, Lightning, Earth, Poison & Petrification, Spacetime, Death and an 8th property used for status attacks which don't fit into the other categories. All eight properties are encoded on a single byte, with each of the eight bits functioning as a flag for one of the eight properties. Non-elemental spells and attacks have all bits set to 0. A single weapon can have multiple elemental and status properties, and a single piece of armor can grant resistance to multiple weapon and status properties, however it seems that spells and enemy abilities never have more than one property (spells like NulAll grant the targets resistance to specific properties, but the spells don't have any elemental properties themselves).

Weaknesses and resistances to elemental and status properties have different effects for damaging spells, status spells and weapons:
 * Damaging spells and enemy abilities deal 1/2 damage against resistant targets, and 1.5x damage against weak enemies.
 * Status spells, such as Quake, Stop, Break and Sleep are automatically ineffective against targets who are resistant against their properties, and have an increased success rate against targets weak against their properties.
 * Attacking with a weapon which matches one of a target's weaknesses (such as attacking a Sahagin with the Coral Sword) is supposed to provide bonuses in the attack formula, however this is bugged and non-functional in the original Famicon and NES releases, however it was fixed in some of the remakes. Elemental weapons are believed to ignore enemy resistances.

Poison and Petrification
Poison and petrification are encoded as a single element / property in the game coding.

Dia
Dia is rumoured to function as an element in some game versions.
