This is my first level idea and its a good one! in it Desna's recon agents have discovered a castle with legions of ghosts and phantoms in it that apear to serve a spirit called Nocturn, the phantom of dreams! this castle also appears to be the source of the horrible nightmares that higher ranked members of the Spiral Order are having. and thus the castle must be eliminated! Through research Nocturn is gaining power via the Dream Machine, which is causing horrible nightmares so it can absorb the fear of the one who is dreaming that nightmare!
First level: (name needed)
Its a graveyard type level except there a many more phantoms in it and all monsters that spawn deal Curse. Starts with a party button fight in a large room similar to the last room of Legion of Almire except there are 4 howlitzer spawn locations and no traps.
1st wave: 5 Caravons, 2 Cursed Howlitzers (like other howlies except they deal curse), and 3 Cursed Bombies (like other bombies except they also deal curse)
2nd Wave: bombie wave: 5 Cursed Bombies, 5 regular Bombies, Grim totem spawns center of the room.
last wave of fight: 1 Cursed Dreadnaught, 10 Caravons, 4 Cursed Howlitzers, 10 Cursed Bombies, and 2 Cursed Almirian Crusaders (like the regular crusaders in LoA except they are faster, their shield surrounds their whole body).
Next up normal graveyard with the dust zombies replaced with caravons, and up to 2 phantoms can spawn per party member, and in the large rooms there will be a Grim Totem.
Last room: similar to the first room except there are traps and the Caravon, Bombie, and Cursed Dreadnaught amounts are doubled, and a Cursed Dreadnaught will spawn in the first wave and there are 2 Grim Totems in the 2nd wave! after this are heart generators, and 6 red treasure blocks near lift and as you aproach the lift the camera will tilt forwards so you can see a huge castle in the distance!
Stay tuned for level 2 and 3 later!
