BuffSystem - "Strange Skill Need Weapon"

[Avisek 8]

Hello,

I added everything from buff system (locale, root, pack) into server (+ added into source of client).. Icons and itemdesc works.. But one thing, that doesn't work is getting effects..

When I click on this item, nothing happens. and in syserr is this:
