Wiki doesn't mention how to use Materia Orb.

Thanks for flagging both of these. Materia Orb: the Glimmer Man tells you to take it to Spindle in Omega Sector, but Spindle was not doing his part. He now forms the orb into one of the Glimmer Man's eleven level 70 weapons, and you pick which one (sword, blunt weapon, axe, spear, pole arm, staff, bow, crossbow, two daggers or a claw). One orb makes one weapon and it costs no Vesos. The choice is final, so check the weapon before you say yes. To re-test: carry a Materia Orb to Omega Sector and talk to Spindle. Idols: the Idol of the Versal Dawn and the Champion's Idol of Versal cannot be obtained yet, so the Grand Idol of Versal cannot be made yet either. They belong to Versal content that is still being made. The Versal idol you can earn today is the Idol of the First Versalmas, from the last quest of the Versal story. Keep it, it is one of the three the Grand Idol is fused from. The wiki pages have been rewritten to say all this and will show it when the wiki is back.
