Equipment skills

Verias

ok i have looked everywhere but i can't find  what each skill does on your equipment ,
i have found this : but the names are wrong,

And i found a topic with this reply :
DEFENSE*
defense  - purpose is to block opponent's normal attack
block/skill defense - purpose is to block opponent's skill attack
immu/immu rate - purpose is to minimize damage from opponent's normal attack even if you get hit.
ironwall/skill immu rate - purpose is to minimize damage from opponent's skill attack even if you get hit.

OFFENSE*
attack - purpose is to increase hero's normal attack.
trick/skill attack - purpose is to increase hero's skill attack.
harm/harm rate - purpose is to increase hero's normall attack effectiveness.
tactic/skill harm rate - purpose is to increase hero's skill attack effectiveness.

but i don't think this one is right since i tested defence and it it did both less damage with normal attack aswell as with skill.

Are there people here that tested these equipment skills , (attack defence immu harm etc, )
or are there some GM that can finaly give a decent answer for this ?

thx
