This is going to be quite a simple guide as the items to get the armour are a combination of other grinds. Utilise the buy back feature in your account manager if needed. You must have completed the "Final Showdown" quest.

• "Build Drakath's Armour"
  • Blade of Awe is required for this quest, follow the guide if you haven't done so already.
  • Blinding Light of Destiny is required for this quest, follow the guide if you haven't done so already.
  • Unidentified 13 can be obtained by completing the "Supplies to Spin the Wheel of Chance" quest from /tercessuinotlim.
    • Head to /ultraalteon and beat up the old man till he drops 3x Relic of Chaos. Turn those in for 3x Unidentified 13.
  • Complete the daily quest at /mountdoomskull 13x for Dage's Scroll Fragments.
  • To get the Le Chocolat complete an unnecessarily obscure and long questline for access to the shop. Just complete the /hyperspace questline, I may make a guide for it but the wiki is your best bet in this situation.
  • Treasure Chests x100 drop from any monster in lore. I suggest going to some map like /icestormunder or something similar with large mob rooms and beating stuff up there.
  • Obtain the Face of Chaos from beating up Drakath at either /ultradrakath or /finalbattle.

After completing this questline you should have a badge and obtainable from the book of lore.
