Zell's Ehrgeiz Ultimate Weapon - FF8 Guide
Ehrgeiz is Zell's Ultimate Weapon in Final Fantasy 8, also known as the only weapon that you can't pronounce the name of. Unlike many of the other games in the series, there is no fancy quest or even location to find this weapon. Throughout Final Fantasy 8 there are Junk Shops and at these shops you can trade items to them in order to receive an upgraded weapon.
Three items are required for Zell's Ultimate Weapon, the Adamantine is easy to obtain once you've gotten the Minotaur Card on Disc 1. Fury Fragments come from a bunch of higher level enemies on Island Closest to Hell.
Required Items for Ehrgeiz:
4 Dragon Skin
1 Fury Fragment
Adamantine: Card Mod the Minotaur Card for 10 Adamantine items. This is the earliest possible way to acquire these items, if you wait until later in the game they become more common. Dropped by Adamantoise enemies (beaches near Dollet).
Dragon Skin: These are most easily farmed from enemies near Galbadia Garden on Disc 1 (Anacondaurs drop them as well as low level Grendels). Or from a location later in the game like Island Closest to Hell, here you can hunt the Hexadragons and Blue Dragons for them... However the best and easiest spot is still the Anacondaurs near Galbadia, if all you want is Dragon Skins go there. Note: Don't Mug any of the enemies or you won't get Dragon Skins at all - they are only dropped.
Fury Fragment: You can farm these most easily from the Island Closest to Hell. If you're low enough level the enemies near Galbadia Garden will drop Fury Fragments too, but anyone over Level 30 will have to hunt elsewhere.
