A random new set piece concept similar to Lunar Island

[Mark2020]

Concept that can be taken by Game Developers as reference

Maxwell's Lab (For Coordinating with the Lore)
A magical lab built by Maxwell since the establishment of the Constant and for him to operate experiments. After his fall, this laboratory was abandoned and dissolved, but somehow reappeared in front of the survivors and Maxwell himself. 

Maxwell's Lab entrance always locates in Desert, Deciduous Forest or Mosaic. To enter the lab, players must lower their sanity to let the obelisks open. The first entering from any player will spawn 3 nightmare monsters to attack them. They will not disappear when the player increases sanity. 

When players are in Maxwell's Lab, they constantly reduce 12 sanity per minute. Hostile Nightmare Monsters sometimes spawn but have some special behaviors: Need to be close to become hostile and only 33% chance drop 1-2 Nightmare Fuel. Nightmare Monsters in here are constantly neutral to Maxwell. Mr. Skits constantly appears in here whenever with how much sanity.

 

Maxwell's Lab is divided into 3 parts:  Maxwell's Laboratory, Maxwell's Forest and Maxwell's Garden. 

Maxwell's Laboratory: Surrounded by some stone wall with different health similar to the Ruin, but with more walls. A science machine and an alchemy engine will always spawn in here. Several indestructible structures spawn in here. 

1.Maxwell's Dark Teleporter: Click it will open the map, and players can click a place in the explored area to teleport into there at cost of a Nightmare Fuel. Opening the map will also make other players' positions visible and players can teleport to there. Need 1 day to be operated again for any players. 

2.Maxwell's Vision Station: Click it will open the map, and player can view the position of different animals or monsters include: Beefalo, Volt Goat, Koalefant, Grass Gecko, Pig, Bunnyman, Chester, Spider, Hound, Walrus, Bosses and other Players. Players can only view the positions of the second that they use the station. Reduce 15 sanity per minute when used. 

3.Maxwell's Nightmare Condenser: A crafting station that provide a slightly lower cost recipe of Nightmare Fuel: 3x Dark Petals or 4x Shadow Cones. These recipes can't be prototyped, must be crafted near the station to benefit from it and replace the original recipes. This makes the players can craft a Nightmare Fuel for just a harvest of one Dark Rose Bush or 2 Shadow Trees.

 

Maxwell's Forest: Some species of mysterious trees abandoned by Maxwell are planted here. They are considered too pretty, dangerous or just simply fail to be approved by Maxwell. All trees spawn with 1-4 in cluster and at least with 1.

1.Shadow Tree: Evergreen converted by shadow energy and no longer physical. Dropping logs and Shadow Cones same as Evergreen but each log has 15% chance to convert to a Nightmare Fuel. Starting from day 1 to day 100, there are chances same as Evergreen to summon Shadow Treeguard when chopped down. Need double the time of Evergreen to grow. Only grow at Night. Can't be burnt. Has a -30/ min sanity aura.

1x Nightmare Fuel can be craft from 6x Shadow Cone.

Shadow Treeguard: Same health and insanity aura as corresponding Treeguard but attack faster, immune to fire. Drop 3x Living Log and 5-6x Nightmare Fuel when killed. Sleep in daytime if pacified with planting normal or shadow Cones. 

2.Tesla Tree: Even Maxwell himself doesn't know how it works. The tree unused by game developers. Similar to lightning rod and attracts lightning. Grow a stage when striked by lightning. Spill the chance of being striked with other Tesla Trees and Lightning Rods. Constantly glowing faintly and glow brightly after being striked. Requires a hammer to be harvested. Dropped 1x Gears(6%) for small, 1x Gears(18%) for normal and 1-2x Gears(36%) for large stage. Drop 1x Tesla Tree Planter (33%) for small or normal and 1-2x Planters (100%) for large. Doesn't grow back to small stage. When players hammer it in normal state or charged state there will be 7% and 28% chances to shock the players for each hit. 

3.Tree Rose: Have a small +6 sanity per minute aura. Can be harvested for 3x Petal in exchange of 6 health. Need 4 days to grow. Rather than like trees, they behave more like Grass Tuft, Sapling and Berry Bush, need to be dug to be replanted. Must be fertilized after replanted but don't need to be fertilized for additional harvest. Unlike Dark Rose Bush, they wouldn't produce Petals in Winter and will wilt in Summer.

4.Kingia: A tree that also grows grass but itself grows very slowly. When in small stage, player can harvest 1-2x Cut Grass every 3 days or cutting it down for 3x Cut grass and 1x Log. In Normal stage, player can harvest 2-3x Cut Grass every 3 days or cutting it down for 4x Cut Grass, 2x Log and 1x Kingia Seed. In Large Stage, player can harvest 3-4x Cut Grass every 3 days or cutting it down for 5x Cut Grass, 3x Log and 2x Kingia Seed. Kingia needs 6 days to grow from sapling to small tree, and 10 days to grow into a larger stage starting from Small stage. Once Kingia is in Large stage, it wouldn't revert to Small stage. The tree itself's growth doesn't be affacted by temperature, but stop producing any cut grass in Winter. Instantly harvestable when grow from sapling to small tree.

 

Maxwell Garden: Spawn some unique plants, several Tallbird Nests, Clockwork Monsters and some sketetons. A Maxwell Statue always spawn in here. All plants in here can't be replanted.

1.Tallbird: Same as those outside. The failed result of one of Maxwell's experiments. As they are created by Maxwell, they are passive to Maxwell in here and neutral to other characters. Nonetheless, they still attack and chase players except Maxwell if their eggs in the nests are taken.

2.Shadow Flower: Players can harvest it for 1-2x Nightmare Fuel at the cost of -5 sanity. Can’t be replanted and burnt. Need 6 days and only grow in the nighttime. After 3 harvests from players, they need to be fertilized by Players with 1x Nightmare Fuel. Doesn't be destroyed when dug in barren state. Has a -30/min sanity aura. 

3.Dark Rose Bush: Players can harvest it for 3x Evil Petals with the cost of -6 health and -10 sanity when harvested. Can't be replanted somewhere else. Need 6 days to regrow. Doesn’t be affected by temperature. Has a -30/min sanity aura.

 

Picking flowers, chopping trees or destroying structures in Maxwell's Lab always have 33.3% to immediately spawn an aggressive Nightmare Monster. This make it very dangerous and risky in Maxwell's Lab.
