I know it's quite late in the game for such a not-very-useful item(unless stacked :D ). I think it's in the Fields of Slaughter.

Where in teh feilds of slaughter? :D

The head orc guy dude, not the Lich. Kratuuk or Kurtuuk or whatever.

Yup, taht's right. Your move

Name atleast four brilliant weapons in the game. HoF versions of weapons not included. The Brilliant doesn't have to be in the name of the weapon, just has to have the effect.

Are they just weapons taht are brilliant, as in good, or do extra damage in some way, called brilliant?

No, any weapon with the Brilliant in it's descriptor. Brilliant means that it bypasses shields and armors.

Oh, come one! You have to know a few Brilliant weapons! Here, I'll help, I now ask for only three different weapons. C'mon, it ain't too hard!

would on e of them be the brilliant flail of wounding, i am lost as to any others, but iam sure i will realise it when you tell me.

Yes it would. Now if I can have someone come up with two more...
Come on!
