[quote=“kosdon”]Anyway 2 questions remain unanswered:
what changes makes Jasper?
Where can I find info about Special skills, Set Affixes appropriate to the item’s class?
For example can I change attack type of bow? or Special skill is 2nd one? And bomb may have illusion skill on it?[/quote]
Weird, because if I check the link that wuce brillis sent you, there is a list of every crystals and their effects :
shinyboxgames.com/NewSite/phpBB3 … &mode=view
And when I search for Jasper I find :
I don’t know how could it be clearer 
did you check his link before asking or you just don’t understand the crystal description?
Special skills and set affixes :
“guides > dictionary” : Dictionary
(You could have search a bit to find this one )
“Items > Legend Design Contest - Patch 1.7” : Legend Design Contest - Patch 1.7
(I agree this one was a bit harder to find 
)
