Types
Materia is separated into five categories of functions in the game: "Command", "Magic", "Summon", "Independent", and "Support". Graphically they are yellow, green, red, blue, and purple respectively. The materia type is determined by a single byte value that is separated into two parts. The upper nybble will be considered the sub-type and the lower nybble is the base type. For base types the values will yield the following results:
| Base | Materia Type |
|---|---|
| X0 | Independent |
| X1 | Independent |
| X2 | Command |
| X3 | Command |
| X4 | Independent |
| X5 | Support |
| X6 | Command |
| X7 | Command |
| X8 | Command |
| X9 | Magic |
| XA | Magic |
| XB | Summon |
| XC | Summon |
| XD | Independent1 |
| XE | Independent1 |
| XF | Independent1 |
Each of these Base Types have a set of sub-types that provide different functions. They are used to determine what function to provide, usually based on the Materia's attribute list. These sub-types have the following functions when equipped:
(If sub-type is listed as 'X' then any sub-type will produce that effect. Other sub-types have no function. Battle effects not mentioned.)
| Independent Types: | |||

- 1 - There are no XD, XE or XF type materias in the game. They are graphically represented as Independent but have no effect.
- 2 - Various in-battle conditions (Cover/Counter) and stat increases
- 2A - 0=Strength; 1=Vitality; 2=Magic; 3=Spirit; 4=Speed; 5=Luck; 6=Attack; 7=Defense; 8=MHP; 9=MMP; 10=EXP; higher than 10 results in memory leaks
- 3 - ONLY works with Materia Index 0Ch (Long Range). Attribute List is ignored
- 4 - Although Enemy Away's first attribute shares a value with Enemy Lure (1), it is handled differently based on index to alter a different memory address from Enemy Lure.
- 5 - Shield is the last magic attack with an index of 35h. The Magic menu prevents access to attacks 36h & 37h
Materia Handler
These are the values assigned to each materia type:
| Handler Value | Type |
|---|---|
| 00 | None |
| 01 | Magic Materia (excluding Master Magic) |
| 02 | Summon Materia (excluding Master Summon) |
| 03 | Base 6 |
| 04 | 20 |
| 05 | Master Command |
| 06 | Master Magic |
| 07 | Master Summon |
| 08 | E.Skill |
| 09 | 41 |

| 0B | Mega-All |
| 0C | None |
| 0D | EXP Plus |
| 0E | W-Materia |
| 0F | some 25 & 35 |
| 10 | some 25 & 35 |
| 11 | 00 |
| 12 | Specifically CounterAttack and Long Range |
| 13 | Base 2 |
It primarily (exclusively?) tells the menu loader which texts to bring up when a menu is loaded.
