Cell Phone

The Cell Phone is an informational item that displays fishing power, weather, moon phase, elevation, distance from the center of the world, time, nearest valuable environment item, movement speed, current DPS, total kills of the last enemy attacked, rare creatures nearby and total number of nearby enemies. It can also teleport the player home, similar to a Magic Mirror. The Cell Phone has one of the most complex crafting trees in Terraria, using 13 base items (and 7 crafting operations), beaten by the Zenith, which uses 14, and followed by the Ankh Shield, which uses 11.

Unlike most other informational items (e.g. its constituent parts), the Cell Phone does not double as an accessory, and cannot be equipped in accessory slots. It instead functions solely from the player's ordinary inventory slots, which puts it into the tool category.

While the inventory screen is open, Cell Phone information is hidden. Instead, an icon is displayed for each information type, each of which can be clicked to toggle their display on or off.

In multiplayer, information from the Cell Phone will be shared with other nearby players on the same team.

Tips

 * Though the Cell Phone is a very versatile and powerful item, obtaining it will often take a huge amount of patience. Some of the required accessories, such as the Metal Detector and the Angler's quest items, may be very time-consuming to come across. However, some ingredients are also relatively common and are found easily.
 * Getting the Metal Detector is easier in Expert or Master Mode as Nymphs have a 100% chance to drop them.

Trivia

 * The Cell Phone's nature as a single "catch-all" device parallels the multi-functionality of real modern s, which have largely rendered once-common appliances like watches, compasses, timers, radios, and atlases obsolete in most cases. The usage of a mirror in the recipe could likewise be a reference how a smartphone's camera may be used as a mirror. The mirror could also be because of the mirror-like touchscreen, which is vastly different from the older model phones which used buttons.
 * It does not seem to be based on any particular real-life smartphone models.
 * The Cell Phone is one of three non-accessories that is crafted at a Tinkerer's Workshop, the others being the Boulder (before 1.4.0.1) and The Grand Design.
 * Although it is a powerful item and has a rarity of, the Cell Phone can actually be acquired pre-Hardmode, as all ingredients can be obtained prior to defeating the Wall of Flesh.
 * The Cell Phone, sharing the Magic/Ice Mirror's use time, is one of the few items qualifying with "snail" speed.
 * This item used to have the most complicated crafting tree of 13 items, but is now beaten by the Zenith, which has 14.
