Item Morale Guide in English anywhere?

[Vilk]

Just quote that this one is wrong:

Jackboots:
Increasing never
Decreasing -5 after each fight.

I checked carefully and does two gremlins fights without to have its morale decrease. I'm using version 1.7. Among condition of those fights, wife Mirabella that was wearing the boots and Seadog in army (no other pirate or robber).

Nobody has a more precise formula for this one?

EDIT: Weird my Jackboots seems different. It has the +1 to the Speed to Pirates and Robbers and the +10% increase of Gold after combat. But unlike description I see at gamebanshee it has a morale of 80 not 50.
Not that I increased its morale no reason to have use it before the two fights mentioned above. Probably a 1.7 change.
