Olduum (Quest) He is in Al Zahbi. Serpents Square. You talk to Dhayaak (spelling is close if not accurate) He tells you to find something. Go to the pool where BLU flag quest is completed in Adyween Subterrane. Take 3-4 pickaxes and hit an excavation point. Took me 2 tries to obtain the key item: electolocomotive. Go back and talk to Dhayaak and he gives you this lightning band. You go to G-8 of wajoam woodlands and trade it to the laypoint. You get a small CS and you will have obtained the Olduum ring. (lvl 60, all jobs) teleports you back to the laypoint.
At 58 it was a snap. Just sneak and invis through some parts. Then walk back or warp to your homepoint.
(I apologize for spelling)Hope I helped.
