[Kristoffer O]

Unit stats gives an approximate gold cost.
Unit equipment gives resource cost.

The res costs of different weapons and armors were scribbled onto an old paper laying around in JK's apartment. Since the development of Dom3 this stat has been removed from the units to each armor and weapon. Thus I can now give you the costs of an armor without having to go through papers on JK's desk (fortunately his desk was often tidy and clean).

There might have been slight changes to the costs since dom2, but not too much.

Shields (buckler, round, kite, tower, ice)
1,2,4,3, 9
Cuirass (leather, ring, scale, chain, plate, ice)
1,3,6,9,15,16
Hauberk (leather, ring, scale, chain, plate, ice)
2,5,9,13,20,22
Full (leather, ring, scale, chain, plate)
3,7,12,17,25
Barding (heavy cavalry)
20-30
Helmet (cap, full, ice cap)
2,6, 3
Weapons (dagger, spear, shortsword, broadsword, greatsword)
0,1,2,3,5
More Weapons (lance, morningstar, flail, mace, axe, battle axe)
2,2,3,1,1,3
Some ranged weapons (javelin, sling, short bow, long bow, comp bow)
1,0,1,2,3
Some more (crossbow, arbalest)
3,4
And ice (knife, mace, blade, lance)
0,2,4,2

Again, these are numbers from dom3, but I think they are valid for dom 2 as well.

This is not the full list. If some weapons are missing you probably have an idea by now what they should cost.
