Once you are this far the next step is to head to the floor under the Pack a Punch machine, where you will find the 4 Elemental statues and crafting areas for each. Next you will need to match up all the Purple Gems on the 4 floating rings using the 4 different switches. Once they are all in line continue under this rings and you will see a Purple Sphere, Shoot it with your lightning staff.

Next head back to Argartha and place the lightning staff in the Lightning Gem Pit, Next kill zombies near this pit to fill the staff with the zombies souls. When it is full you can remove it and you now have the Ultimate Lightning Staff or Kimat's Bite.

Once upgraded to Kimat's Bite, it shoots lightning bolts with much more power and damage than its previous version. You can also hold down the firing button in order to charge it up, at the cost of more ammo per charged shot. When charged and released, it fires a charge of lightning, and will shock and easily kill nearby zombies. It also gains a secondary "attachment" called Sekhmet's Vigor which when activated by pressing right on the D-Pad, will cause the player to flip the staff and use the bottom end. This can be used to revive a downed player by "shooting him."
