Incorrect class

i am trying to make rank 9 quest work(it had some little bugs )
what i did:
copied the quest rank IX weapon and edited with items id and requirement for each class but when i try to get the quest it says Incorrect class
P.S. i checked already twice and the class is correct Blademaster cant take my "rank IX Blademaster" quest
any idea why it doesnt work the class requirement??

well looks like it wasnt that the problem actually it seems like any of the 6 quest leads to the quest related to venomancer....
ex. i take quest A but it opens me quest C, same thing if i try to open quest B it opens me again quest C...
strange
looks like linking mistake but in elements.data is all right and in the task data they shouldnt be connected in any way...

Check dialogs tab on sTaskEdit and check if the "task link" match to the correct quest id.

tnx romulan that really helped me
