About PP increase (signed)
Even though the game considers only the first two bytes of PP increase, the developers left two more bytes.
This was probably done so the table has the same structure as the Level-up stats table.
Item type
Not fully known. Values range from 0 to 9:
| 00: Weapon |
| 01: Body armor |
| 02: Headgear |
| 03: Armgear |
| 04: Food |
| 05: Status healer |
| 06: Damaging Item |
| 07: Special Effect Item |
| 08: Key Item |
| 09: Unused Key Item |
Key item flag
Seems to be 01 for non-key items, 00 for key items.
Equip flags
This is a bitfield indicating who can equip this item:
- 01 = ?
- 02 = Flint
- 04 = Lucas
- 08 = Duster
- 10 = Kumatora
- 20 = Boney
- 40 = Salsa
- 80 = ?
Status ailment protection
Indicates how much to protect against certain status ailments. A more negative value means more protection. Each value is a 16-bit signed integer. There are 11 values, corresponding to the table below:
| 00: Poison |
| 01: Paralysis |
| 02: Sleep |
| 03: Strange |
| 04: Cry |
| 05: Forgetful |
| 06: Nausea |
| 07: Fleas |
| 08: Burned |
| 09: Solidified |
| 0A: Numbness? |
Elemental protection
Similar to the status ailment protection, an item may also protect from elemental damage taken from PSI or Bomb items. Each value is an 8-bit signed integer. There are 5 values, corresponding to the table below:
| 00: Neutral (PK Love, Starstorm, Ground) |
| 01: PK Fire |
| 02: PK Freeze |
| 03: PK Thunder |
| 04: Bombs |
Attacking type
These bytes are only considered if the item is a Weapon.
The first byte detemines what battle action the normal "Bash" one should become when the weapon is equipped.
This is used to make the battle action name change to "Kick", "Shoot" and other such names.
By modifying this value, one can make characters who aren't supposed to use PSI use them or use the battle action Consider.
The battle action name pointers to the Battle text are obtained by adding 0x9D to the value of the first byte.
Boney's battle action won't change name if it's an attack, but it will change name if the action becomes a skill.
Info chunk
PSI data, Item data, Battle skills table and Battle actions table all share this group of 0x28 (40) bytes.
It is called Battle Info chunk.
Item uses
If the third byte value is 01, the item will be usable only one time, in battle, before disappearing.
If the third byte value is 00, the item won't disappear after the use.
