In this zone you will have to collect 6 items.
Recipe :: Progression - Completed Underfoot Stone
These drop randomly in the zone, but people have reported having better luck off of named NPC's. Keep in mind you can buy individual pieces from Borat using zone kill points. It won't show up as checked off in your quest window if you buy any, but it's no issue, just combine and do the turn-in once you have all 6.
Once you have these items combine them in your Universal Assembly Crate to make Complete Underfoot Stone. Turn in your Complete Underfoot Stone and Dragon Infused Hero's Stone Rk.III to Borat in The Hole to get your Underfoot Touched Hero Stone Rk.I.
