The latest area added to the Christmas games, the Rift Dungeons are new bonus dungeons. They appear in first screens of the the initial dungeon areas, and contain new challenges. This includes battles with Tux, Itharak, Hidden Death, and Thomas Lobo.
Once you defeat all four opponents the last one will give you the "Achievement C". With all three Achievements you can turn them in to get a "Dew Bottle".
TownCity (Klos's Dungeon)Edit
This rift dungeon is a bustling city, with winding paths. You must navigate the paths, make an odd decision, and get help from someone you'd least expect.
Item: Everlasting Dew
Mainframe Core (Jim's Dungeon)Edit
In this rift dungeon the idea is to turn off Jim's computer to get his attention. The following items must be turned off.
After that you have to be timely to hit off the emergency switch.
Item: Game Fuel Lemon Dew
Fiend Nest (Jacob's Dungeon)Edit
There are many NPCs here and getting caught by any of them will take you back to the start.
Item: Zero Wing
Graveyard (Trevor's Dungeon)Edit
In this rift dungeon you must brave the traps laid by Trevor. Be careful as the path may be winding, but it is better than being at his mercy.
Item: Sangrita Blast Dew
