.ITM holds item definitions. The record length is stored in BINSIZE.BIN.

This lump will eventually be replaced with items.reld (This incomplete feature is not in nightlies)

Formal Specs[edit]

Offset	Data	Meaning
0	VSTR(1i+8i= 18b)	Name
9	VSTR(1i+36i = 74b)	Info (in zenzizenzic and older, length was 35, with INT at 45 unused)
46	INT	Value (does nothing except provide default buy + sell values in stores)
47	INT	Attack when used in battle (attack num+1)
48	INT	Attack when used as weapon (attack num+1)
49	INT	Old Equippable as (obsoleted in fufluns read bitsets in INT 239 instead) 0 = NEVER EQUIPPED 1 = Weapon 2 = armor 1 3 = armor 2 4 = armor 3 5 = armor 4
50	INT	Teach Spell (attack num+1)
51	INT	When used out of battle: > 0 is attack num+1, < 0 is -1 * textbox number (box 0 can't be triggered)
52	INT	Weapon Picture
53	INT	Weapon Palette, or -1 for default
54	INT	HP bonus
55	INT	MP bonus
56	INT	Attack bonus
57	INT	Aim bonus
58	INT	Defense bonus
59	INT	Dodge bonus
60	INT	Magic bonus
61	INT	Will bonus
62	INT	Speed bonus
63	INT	Counter bonus
64	INT	MP~ bonus
65	INT	Hits bonus
66-69	INT * 4	Equippable by (first 64 bits, rest are separate, in INTs 211-238)
70-72	INT * 3	Bitsets 0-7 Weakness to elem 1-8 (Obsolete, see #Note 1) 8-15 Strength to elem 1-8 (Obsolete, see #Note 1) 16-23 Absorbs elem 1-8 (Obsolete, see #Note 1) 24-47 Undefined
73	INT	Consumability 0 = Unlimited use 1 = Consumed by use 2 = Cannot be sold/dropped
74	INT	OWN ITEM tag #
75	INT	ITEM IN INVENTORY tag #
76	INT	IS EQUIPPED tag #
77	INT	EQUIPPED BY ACTIVE HERO tag #
78	INT	Frame 2 "Handle" point X coordinate
79	INT	Frame 2 "Handle" point Y coordinate
80	INT	Frame 1 "Handle" point X coordinate
81	INT	Frame 1 "Handle" point Y coordinate
82-209	FLOAT * 64	Elemental resistances. 1.0 is 100%, which is the default value, meaning 'no change'. These are "merged" into the elemental resistances of heroes which equip the item according to one of several possible formulae. ^{#Note 1}
210	INT	Maximum inventory stack size, or 0 to use the default, gen(genItemStackSize)
211-238	INT * 28	Equippable by (bits 64-511) - rest in INT 66-69
239	INT	Equip slot bits (starting in fufluns) 0 = Weapon 1 = armor 1 2 = armor 2 3 = armor 3 4 = armor 4 5-14 = unused 15 = equip bits initialized. If this is off, read obsolete int 49 instead

Note 1[edit]

If fixItemElementals is OFF, then elemental resistances should be loaded from the absorb/weak/strong bits (default to 1.0, multiply by -1.0 for absorb, 2.0 for weak, 0.12 for strong).

If fixItemElementals is ON then elemental resistances should be loaded from the array of 64 FLOATs, and the old bits are garbage.
