The Cursed Oasis is an unusual dungeon, composed of two overlapping realms. You will be forced to handle exploration and popcorn monsters in unusual ways. Curses play a large part in this dungeon, so characters that rely on resistances, particularly monks, will struggle.
There are no ordinarily no subdungeons in this dungeon, but the Smuggler’s Den will still appear if you prep it.
Monsters: Bandits, Dragon Spawn, Animated Armors, Thralls (Poisonous and Mana burn), and Shades
Special Rules: You gain one stack of Cursed whenever you gain a level in this dungeon. This even affects Crusaders, which are otherwise immune to curses. When you have any stacks of Cursed, you will find yourself in the cursed realm.
The normal realm is a very large and open dungeon containing relatively few walls, with an oasis in the center that can only be explored by LEMMISI. Monsters include Bandits, Thralls, Animated Armors, and Dragon Spawn. In addition, while exploring, you will sometimes encounter lifedrain by an invisible monster. These are actually the Shades in the cursed realm, which you can walk through in the normal realm.
If you have any stacks of Cursed, you will immediately enter the cursed realm. In the cursed realm, most dungeon features on the ground are not available: glyphs, potions, boosters, shops, unused altars, gold piles, the Smuggler’s Den subdungeon. Even the dungeon exit vanishes. Active altars, which remain available, are the only exception. Thus, before fighting a Bandit or gaining a level, you should have a plan for killing enough popcorn to clear your curses if you still need to exploit these resources.
The Shades become tangible in the Cursed Realm and provide a valuable source of XP and Curse-clearing. However, because they can blink into blackspace and then lifesteal again, it is risky to fight higher-level Shades before the dungeon is mostly explored.
The Cursed Realm also features a large number of Erosive Eelroots in the locations of shops, boosters, potions, and gold piles. The dungeon is open enough that they don’t usually interfere with getting around; they are useful to build up extra stacks of Cursed so you can avoid getting kicked out of the Cursed Realm before you want to.
The primary boss of the Cursed Oasis is the Cursed Dragon, the only monster that appears only in the normal realm. He has decent but unremarkable stats: 546 HP, 86 attack, Retaliate: Fireball, and magical attack. Before the Curse Shade is defeated, he also has Curse Bearer, so you won’t be able to fight him before you’ve taken care of the second boss.
The secondary boss of the Cursed Oasis is the Curse Shade, who appears only in the cursed realm. He has only 159 HP and 60 attack, but 60% physical and magic resistances. He also has both 40% and Blink, so you won’t be able to carry much if any blackspace between fighting him and the Cursed Dragon. The Cursed Shade drops the Dragon Soul item when slain, which provides 8% resistances (marginal at best even if you weren’t carrying around a stack of curses) and forces you into the normal realm.
