Status Effects

There are 31 Status effects in FF7. In attacks and items they are referred to as a 32-bit longword. In Materia they are only 24-bits so the last 8 cannot be affected. In weapons and armors they are represented as an index. Weapons have a low inflict chance.

If “Dual Drain” is inflicted without “Dual”, the game will crash. Section 4 of Terence Fergusson’s http://www.gamefaqs.com/console/psx/file/197341/22395 Battle Mechanics FAQ (a little more than half-way through) describes each of these statuses with great detail.
