How do you get the ancient spear pieces on my Lego network

go on the bionicles product page and look for tarix then you click on the glatorian symbol and he will give you red pearls or an ancient spear fragment
i just go to berix's Page. i keep trying to do it on tarix's page and he keeps giving me red pearls.
Update: now that you cant do that any more you have to trade 4 the fallowing:1 fragment 1,2 and 3 and 2 red pearls to build it
