Kail's Magic Coin

First, you must Become a royal coin collecting member..Once you are a royal coin member, talk to Head Blacksmith Vergara in Hunter's Village to activate the quest.
He tells you to hunt on the Forsaken Plains for Fallen Orcs, Fallen Orc Shaman, Fall Orc Captains, and Fallen Orc Archers to obtain Kail's Coins. They drop as follows:
Fallen Orcs: Kail's Silver Basilisk
Fallen Orc Archers: Kail's Gold Golem
Fallen Orc Shamans: Kail's Blood Dragon
Fallen Orc Captains: Randomly drops Kail's Silver Basilisk, Gold Golem, or Blood Dragon

Some Fallen Orc Shaman morph into a Sharp Talon Tiger after being attacked. The shaman that do this do NOT drop the coins. The same shaman always morph, so once you see one shaman spawn morph you know that it will morph everytime. After morphing, the morphed shaman (who is now a Sharp Talon Tiger) will drop stolen infernium ore if you have the Stolen Dignity Quest active.

Each A-grade recipe requires 10 of each coin type. Going back to Vergara you will see that you also need coins from the regular coin quest to obtain one in addition to these Kail's Coins. Bear in mind that 1 Blood Basilisk is equal to 100 Blood medusas, 1 Silver Dryad is 100 Silver Unicorns, and 1 Gold Giant is equal to 100 Gold Wyverns. In general, the low A-grade takes 2 Silver Dryads and the top A-grade takes either 3 Blood Basilisks or 3 Gold Giants. All take 10 of each type of Kail's Coins.
