Things You'll Need
Instructions
Obtain the Royal Ludroth Coins by going to the Water Arena. Enter the grudge match with Royal Ludroth. You have 50 minutes to finish hunting Royal Ludroth. Upon succeeding, there is a chance you will receive a Royal Ludroth Coin. You will need to collect four of these coins.
Obtain the Lagiarcrus Coins. (You do this in a similar manner to collecting the Royal Ludroth Coins.) Go to the Water Arena and enter a grudge match. This grudge match will be hunting Lagiacrus. Again, you have 50 minutes to complete this match. Upon completion, there is a chance you will receive a Lagiacrus Coin. You will need four of these before you can make the Wyvern King Eye Patch.
Obtain the Barioth Coins by going to the Land Arena and entering the grudge match with Ice and Fire. Again, you will have 50 minutes to hunt Ice and Fire. After succeeding, you will have a chance of receiving the Barioth Coin. You will need four of these coins as well.
Collect 10000z. If you are strong enough to have completed the three grudge matches required to obtain the Royal Ludroth, Lagiacrus and Barioth Coins, you should already have more than 10000z. If you do not, sell some of your unneeded items until you have 10000z.
Open the recipe list. You should see in the recipe list for accessories that the Wyvern King Eye Patch is available for creation. Simply select it for creation, and you will now be in possession of the Wyvern King Eye Patch. If you do not see the Wyvern King Eye Patch in the recipe list, it means you have not collected all the necessary coins.
