Part Two: Collecting the Lineage2 Gold

From what I have seen, the Ivory Tower area is the best place to collect coins. This area spawns several different monsters that will drop all three types of coin. The Timak Orc Soldiers will drop Blood Medusa Coins very often. Gold Wyvern Coins will drop once in awhile from the shackles in the circle of the Ivory Tower. Silver Unicorns will also drop fairly often, though not frequently, off the Formors and Formor Elders. Though I have not tried fighting the Ol Mahum and Ol Mahum Warriors, I have heard from them that they will drop Silver Unicorn Coins a bit more often than the Formors/Elders.

Thanks for your supporting, and new infor will come soon, hope you have fun when playing games ! Good luck ^^
