thought of a new dungeon idea, had to put here.
as some of you may have guessed, the blue hole dungeon is based on the blue hole in real life, a deep strangely circular hole in the ocean.
to start out the dungeon would have a little darkness, increasing to nearly complete darkness by floor 50, almost requiring some way to negate it, as you get deeper you’d transition from normal water types in the upper floors, deeper water types such as wailord as you go down and eventually having solely deep sea pokemon.
from floor 50 to 60 things will get somewhat strange, while you’ll still have all the deep sea pokemon you’ll also get some stranger pokemon, such as ghost types and maybe a pokemon or 2 thats completely out of place like a litleo until you’d eventually reach floor 60 and get to the midboss
Surprise! it’s Nihilego and the arena is labeled ultra deep sea, after defeating it you’d potentially get it’s heart slate, or recruit it not sure how ultra beasts are going yet.
you think you’re done with the dungeon now? well your wrong it keeps on going!
now labeled ultra space instead you’d be in a strange place that almost seems to be falling apart, and everything would still be dark!
Dark, ghost and, psychic types would be common here with a smaller amount of deep sea water mons and the occasional random mon too.
After a bit the tileset would transition to a cave, and then a grassland, and finaly a temple having appropriate mon types for all these areas, additionally things would get brighter over time with the darkness completely removed once you reach the grassland tileset.
during these floors secret rooms for all the remaining ultra beasts as well as necrozma could generate, having a portal sprite instead of golden stairs.
when you finally reach floor 99 you’ll be on top of an ancient altar, during the day it would have a sun emblem and Solgaleo and during the night a moon emblem with Lunala. When beaten Solgaleo would have a chance of dropping a Sun crest, and Lunala a Moon crest, these items would act as costumes for cosmog, cosmeon and, necrozma, causing them to gain the corresponding forms apperance, additionally increasing the stats of cosmog and cosmeon.
finally you’d reach the treasure room which would have various relics and valubles, as well as themed items for the time of day, additionally using honey here would spawn 1 cosmog once.
what do you guys think? the later stuff with the sun and moon crests would likely be too hard to implement but I think the rest could work.
