Stone Age

The Stone Age is the first Age encountered in the game. There are no ores revealed in this Age, as they are all hidden. The main resources are plant fibers and rocks. They are found by destroying grass and the stones on the ground. This Age is divided into two parts: a Tutorial segment of Advancements and the normal system of advancements. The tutorial part is completed by crafting a Work Stump. There are more items and mobs revealed after completing the tutorial. The next Age is the Bronze Age.

To progress to the next age, you must build a Melter from Tinkers' Complement.

Materials
Most of the tech requires flint and wood, but some of the advanced recipes require Shadow Gems, String, and Leather.

Many of these materials require animals. The easiest way to get an animal to your base is by carrying it using shift right click. This technique also works for carrying most devices, such as crafting tables, kilns, chests, etc. String can be easily made using a work blade on fleece that is sheared from a sheep.

Leather is obtained by going through a multi step process. It involves killing an animal, which gives the hide. Crafting the hide with a Flint Work Blade creates around four Raw Hide. The Raw Hide can be combined with Salt and a filled Water Skin to make Salted Hide. The Salted Hide is dried on a Drying Rack from Tinkers' Construct, which gives Dried Hide. That can be combined with the filled Water Skin and Resin to make Wet Tanned Hide. That is then dried on the Drying Rack for Leather. Resin is made by using the Work Blade on a Wood Log to get Bark, which is ground on the Grindstone. In the Stone Age, you will need to use a fluid bladder for leather, but a wooden basin is highly recommended as soon as you reach the next age, as you will be making a lot of leather.

A large portion of this age also revolves around Totemic and the use of ceremonies to summon buffalo and red cedar trees. Buffalo are extremely useful for their pelts, which can be used for leather, but their teeth are also required for the flame grilled whopper. If you have the resources available, a second flame grilled whopper may be useful for automation of cooking, even throughout ages 4 and 5. Buffalo are also the most effective creatures to use with the chopping block, press, and grindstone.

Mobs
Trumpet skeletons, creepers, spiders, and zombies all appear in the stone age. Any mobs that are able to hold weapons may spawn holding sharp bones (40% spawn chance) or trumpets, and possibly wearing leather (50% spawn chance) or wolf armour (15% spawn chance). Trumpet skeletons may "doot" their trumpet, causing a player to jump back. This may result in the player falling off an edge or being thrown into another mob. Trumpets have a very low drop rate and are coveted items as a result.
