Journey Mode

Journey mode is an option that can be selected during world and character creation. It allows the player a large degree of customization options during gameplay, including difficulty sliders. Journey mode is a difficulty in which characters start with extra equipment compared to classic characters and have access to the Power Menu. Players start with an Iron Shortsword, an Iron Pickaxe, an Iron Axe, an Iron Hammer, a Finch Staff, 100 Torches and 100 Rope. The player also has a pair of Fledgling Wings equipped. The Fledgling Wings are exclusive to Journey mode, but is the only Journey mode-exclusive item. For worlds, Journey mode is a world mode like Normal, Expert mode or Master mode. Journey mode characters can only play in Journey mode worlds, and likewise, Journey mode worlds may only be entered by Journey mode characters. Enemies in Journey Mode have half the health of their Normal Mode counterparts by default, but this can be changed with enemy difficulty slider found in the power menu.

Power Menu
The Power Menu contains a number of options to customize the player experience.

Duplication
This menu allows the player to instantly duplicate any previously researched item indefinitely. The menu has tabs for different item categories (such as materials, blocks, weapons, armor) and is searchable.

Research
Certain amount of resources can be spent to unlock that same item for unlimited spawning in the Duplication menu. The amount that must be sacrificed varies by item, such as a single weapon, 3 Treasure Bags, 50 Acorns or 100 wood.

Time
Allows the player to pick from four preset times (Dawn, Noon, Dusk, Midnight) as well as the option to freeze time and alter the rate at which time passes from ×1 to ×24.

Weather
Allows the player to control the weather, including specific sliders for Rain which moves from Clear Sky to Monsoon, and Wind Control which allows the player to choose the direction and speed of the wind. The player can also disable the ability for weather to randomly change.

Godmode
Enables or disables Godmode. In Godmode, players will never take damage or knockback, will have an infinite amount of time in water without breathing, and magical attacks will not cost mana.

Increased Placement Range
A toggle option which greatly increases the range at which a player can place/destroy blocks. By default, this is on at the start of every Journey Mode world.

Infection Spread
A toggle that can stop the spread of evil biomes or The Hallow.

Enemy Difficulty Slider
This slide can be set anywhere on a scale from 0.5× to 3×, equating to game difficulty. At the bottom with 0.5× is Journey mode moving up through Normal mode at 1×, Expert mode at 2× and Master mode at 3×. Moving the slider will enable all rewards obtained in the chosen difficulty mode. Expert-mode exclusive items and Master-mode exclusive items are dependent on this slider in Journey Mode.

Enemy Spawn Rate Slider
This slider allows the player to control the Spawn Rate of enemies on a slider anywhere from 0.10× to 10× the normal rate.

Trivia

 * The God Mode icon is a reference to the game Doom, which has a similar God Mode icon.
 * Journey Mode is known as "Creative" in the Terraria code.

 * Alternating Day and Night time also counts as random chance for Events like the Blood Moon to occur, if the requirements for these events are met.
 * Some bosses, like the Eye of Cthulhu, have more health on Journey Mode with a 1.95x multiplier than on Master Mode.
