So Galados Isle and Tschilly Peak have quests to introduce the player to them. Well, people (like me) might have expected a quest to introduce them to New Lumos, and therefore not have gone there for at least while after defeating the Darkest Lord. So I came up with a quest with a new dungeon, new boss and featuring rare enemies.
Quest level - 21-25
Location - New Lumos (Hidden District)
Type - "See if [place] is safe!"
Monsters:
Harpy
Baby Dragon
Ammonite Fossil
Gold Glyph
Delicious Snurp (map exclusive)
Boss
Dark Golem
Notes
The Dark Golem, the boss of this area, can be refought in the Tower of Dread on the Ground floor. This means completion of the quest is required for unlocking the Tower of Dread.
I would've made the boss the "Traveler"otaur, but that would've been too much of a parallel between the King Cow, the first proper boss of Lumos. Do you think the "Traveler"otaur would've fit better considering it's rarity?
