I found my old post ( thank's for search ability! )
and you can read it here...

It show's that I had same problem in early this year and I dind't
stay to think it so long... Life goes on in Gael Serran, and that
'magic' spear is only one stupid stick with no good use.

My topic was 'Magic Spear and Sack of Yellow... ' I first tought that
sack of yellow would be that stink powder and wandered why Shinwiki wouldn't
gave it to me... ;)

however i found Shinwinki's spear to be quite useful in my game as it NEVER breaks, and deals decent damage too.........! [img]graemlins/saywhat.gif[/img]

I don't think that's a special feature for Shimwiki's spear Ukabu. :D There seems to be a tughen bug when it comes to weapons and armor as well. No weapon I have ever blessed with vine magic has ever broken in my games. Heck I have even played through the game three times with an enchanted sword that was unbreakable. [img]smile.gif[/img]

everyone has their own strategies to playing W&W, for me it was to take the spear and put it to good use. nothing in this world is free right? so i take the spear as a reward for my services! :D
