Seed: 1131161469
World Size: Small.
World Evil: Crimson or Corrupton Both Work!
World Difficulty: Expert (Expert mode has the Rainbow Gun 100% however you can try using Normal mode which should most likely work however I am not sure for now)

Key Points:
Rainbow Gun.
Waterbolt Magic Weapon In Entrance of Dungeon.
2 Pyramids with Double Jump Item (2 Sandstorms in a Bottle.)
Very Big Dungeon For a Small World.
Very Flat and Very level (looking at screenshot number 2) mostly which is super helpful versus annoying.

Description: The Rainbow Gun is inside a WOODEN CHEST (not gold) inside the dungeon. If you use this seed it gives you a very overpowered head start when beginning as a new character without cheating really. You get the rainbow gun which is supposed to be a post-Plantera weapon that is difficult to obtain. Also you get a water bolt which is powerful even in early hard mode and will carry you through pre-Hardmode NO PROBLEM! Also you even get a cloud in a bottle that is very very useful in the beginning and throughout pre-Hardmode and for crafting.

Key Points: Big Hollow Tree right next to spawn so you can build your house their easily and room for NPCs. Corruption right next to spawn to the left. Very many chests with no digging required. Each ocean has about 4+ chests I believe. Also 3 Heart Crystals without digging required right when you enter Jungle from spawn side.

Description: Mostly pretty flat world which is really helpful and the opposite of annoying requiring less maneuvering and time to get across or get to places. Use the picture for guidance!

Мир Размер: Маленький.
Мировое Зло: Коррупция.
Мир Трудности: ваш выбор. :)

Ключевые вещи: Большое пустое дерево возле спайна, чтобы вы могли легко построить свой дом и комнату для NPC. Коррупция возле спайна налево. Очень много ящиков с сокровищами. Я считаю, что в каждом океане есть около 4 ящиков с сокровищами. Также 3 Кристалла Сердца без рытья необходимы, когда вы входите в джунгли со стороны спайна .

Seed: Torreriu
World Size: Small
World Evil: Crimson
World Difficulty: Expert. (However Normal will most likely work too give it a try!)

Key Points: 2 Pyramids both containing Flying Red Carpets. Waterbolt pretty close to Dungeon Entrance. 2 Crimson Entrances Right Next To Each Other and They are Connected! Only one Crimson biome. Dungeon is a respectable size. Map is 75% completely flat.

Description: Each pyramid has a Flying Red Carpet so this map is perfect for several players doing a new characters play through. One of the Pyramids is very close to the spawn if you go right. Spotted quite a few above ground Treasure Chests or I mean that don't require any digging. Very helpful Crimson area with two entrances and connected so making the map only have one area with Crimson and not two or three keeping it very containable and managable; Only One Crimson Biome.

Description: This world seed has very small corruption areas. Also their is a huge pyramid! Also this world is mostly flat which is pretty rare! The jungle area is pretty huge and does not have evil on the sides of it which is considered very rare in random generating of maps. The dungeon is placed basically in the ground there's like a hole to enter into it it looks really cool in the sand biome especially. A good; very long flat spawn is included as well.
