Instructions
Fight as many Flying Wyverns as you can find while completing quests throughout "Monster Hunter Freedom 2." Flying Wyverns are the only type of monster that count toward unlocking the Gold Rathian and Silver Rathalos missions.
Go to areas where you are more likely to find Flying Wyvern type monsters. Different types of Flying Wyverns prefer living in different climates. For example, Gravios and Basarios are frequently found in volcanic regions; Khezus are often found dwelling in dark, damp caves; Diablos live in deserts; and Rathalos and Rathians reside in forests, volcanoes, swamps and hills.
Kill a total of 100 of any species of Flying Wyvern to unlock the Gold Rathian and Silver Rathalos quests in your quest menu.
