Dragon Nest Closed Beta June 15th~20th

First thing I died to was the fire goblin thing since I kept getting burned.

You upgrade at any blacksmith, +1 to +8 only cost bronze coins (in cbt). You're supposed to be able to convert frags into whole Onyxs but you needed an item not in the game during cbt.

Actually, you just need three Onyx Fragments for a Crude Onyx, but you needed to Craft them, and Crafting wasn't in CBT.
I got all my Crude Onyx from Sanctuary Nexus. Easy/Normal mode runs got me 2-3 per run.
