Hello gioz, and welcomne to the Forum <img src="/ubbthreads/images/graemlins/wave.gif" alt="" />
I think you are at Divine Divinity, i think there is no enchanting in BD.
Ok, you need the Warrior Skill for enchant weapon.
The rest can you take from this
Page from Kiya.
And maybe this thread will be moved in the DD Part of the Forum.
