The Ancient Spear Fragment 1 is one of the three mailable Items from the 2009 BIONICLE campaign that are required to make the Ancient Spear.
How to Obtain
The Ancient Spear Fragment 1 is no longer legitimately available. However, there is a workaround.
Users could obtain the Ancient Spear Fragment 1 randomly at Tarix's or Berix's LEGO Product Page by clicking on the Glatorian symbol in the lower right every six hours. Users may get a Red Pearl instead of any Ancient Spear Fragment. Users could not get more than four Fragments/Pearls per day due to the six hour intervals. Tarix and Berix's Product Pages have both been taken down.
Workaround: Every six hours, go to Berix's cached product page. (Limit 4 items per day) or go to Tarix's cached product page.
Note: Once the Glatorian Contract has been built, no more Spear Fragments can be obtained and the message "Slow down, my friend. I can only collect four per day, so come back later" appears every time.
Trivia
It is the hardest part to find of the three Spear Fragments.
