identify skill

[darkkken]

i noticed that as time passes my character who is not a thief and has no identify skill per se is able to identify some things, but mostly not if it is 50% or less it is usually not - does intelligence influence this??? if not what does?
TIA for any help

my character, who is a fighter-mage-knight, has intellect of 45 and i can't identify anything

I think all items that identifies for 0 gp in stores, a char with 0 identify has a 50% chance to identify.
