Elements 0x0A to 0x0E are considered Physical elements, though not enforced as such and show up on physical attacks.
Non-elemental attacks, such as Bahamut’s Flares, have no element selected.
Note
Display: The names of elements 0x09 to 0x0E are never mentionned in the game. However, they are stored as battle text for the purpose of sensing. Hidden / Ultima has no name mentioned in the battle text.
Status Effects¶
There are 31 status effects in FF7.
In attacks, items and accessories they are referred to as a 32-bit bitmask.
In materia they are stored as a 24-bit bitmask so the last 8 status can not be used.
In weapon and armor they are represented as an index. Weapons have a low inflict chance.
