The wyverns have been quiet ever since Tani’s kidnapping was foiled, but now there are suspicious rumblings coming from their lair once again. Head on over to the Wyverns’ Den and go inside, where you’ll find some wyverns on the floor. It seems like they have been trying to find a new successor to replace the warlord you defeated earlier in the game, but an exiled member came back with a vengeance, only a bit infected. You’ll find Twygg, a level 51 Tainted Monster in the same room as you fought the boss. While he’s definitely strong, it shouldn’t really take much to defeat him, especially since he seems to just like spitting projectiles and doing the random weapon swings. You’ll receive a Phoenix Tear for defeating Twygg, plus get your usual rewards once you speak with the pirate back at the base.
