Winter is Coming
No preparations are allowed in this dungeon
The dungeon will always have the IMAWAL and BYSSEPS glyphs, and has regular shops. There are no altars available for worship. You begin with a "contract" in your inventory that can be converted for 100 CP.
Frigid Corpse: Undead, Bloodless
The boss Shard is immensely powerful, with wicked damage, health, and resistances. However, he is only 7th level, meaning an 8th level Assassin can kill him instantly using swift hands. As a result, the real challenge of this dungeon is leveling up from the other monsters.
The easiest approach to this dungeon is to play as a Goblin, allowing you to convert things for experience points. It's basically impossible to lose if you follow this route; simply explore the map, convert all the glyphs and the contract, then execute every monster with swift hands. There's enough XP to take you to level 8 even without buying items from the shops to convert. If you wish to win as other races you will need to aggressive pursue bonus experience. The best approach is to attack higher-level Meat Men using poison and petrify low-level Frozen Corpses or Frozen Trolls to multiply your earnings. If you have not yet unlocked goblins, your best option is to play as a Human. Even without the goblin, this is still one of the easiest challenges in the roster.
