Getting there
Talk to any Warper and choose Dungeons > Nidhoggur's Nest > Level 2
(nyd_dun02). Teleporting is blocked on this floor, so walk it.
The nest's first floor (nyd_dun01) is a PvP map, so the Warper doesn't
send you there.
Monsters
Draco and Draco Eggs, Aqua Elementals and Dark Pinguicula fill the floor. Rata and Duneyrr, two level 107 heavy hitters, return every 15 minutes. Come geared.
Nidhoggur's Shadow
Nidhoggur's Shadow, a Tier IV MVP, returns 4-6 hours after it falls. It is a fight for a party of 5+: 60M HP, a shadow strike with a 1 s cast, splash hits, Dispel, and three waves of adds (Draco, then Aqua Elementals, then Dark Pinguicula). How MVP tiers fight: MVP Bosses.
