I found some items while I was killing RB with my clan, in them there are only describing: Obtained by attacking a Raid Boss. You can assemble this Life Crystal and trade it for something useful.

Okay... now the question What can I do with this items? If I can exchange wich NPC will do that? And what can I possibily get with?

Thx in advance =**

if u play on kamael or hellbound server u can do many things with life crystals.. like learn transformations.. otherwise sell it to a clan leader.. they need it to get clan skills...
