Medieval Age

The Medieval Age is the third Age encountered in the game. Four ores are revealed in this Age: Iron, Gold, Lapis lazuli and Rock crystal ore. Some of the new tech includes tinkering, exploration and astral sorcery mod. The previous Age is the Bronze Age and the next Age is the Industrial Age.

In order to progress to the next age, you need to craft a Coal Engine. This is a deceptive task in how simple it appears - this age has the least number of advancements in the main progression, but notably the coal engine will require the player to travel to the Twilight Forest and slay the Naga, Lich, Ur-Ghast, and Hydra. Prior to this, the player will also need to visit the Betweenlands, which is comparable to starting the tutorial again, except with more dying this time. 10/10 would recommend.

All in all, the Medieval Age features large amounts of exploration in a variety of interesting new locations, and features the perk of Journey Map as an available unlock!

Materials
Steeleaf is a very useful material introduced in this age, because it can be used with Tinker's Construct items to quickly replenish their durability. Of course, the main materials introduced in this age are the ores gold, iron, lapis, and rock crystal. The rock crystals are extremely useful for crafting in Astral Sorcery, partially for the recipes including them but also for the liquid starlight they produce in a lightwell (they can produce much more than aquamarine - despite what JEI may say). Gold is most useful for making Tinker's casts and buying things in the market. Iron is useful for making stronger items, as well as star metal ore. Lapis is useful for luck on pickaxes, nocturnal powder, and a few other small recipes.

Stardust is another important material in this age - and it is accessible through two recipes! - either by starlight infusion in the Astral Sorcery multi block structure, or by crafting it in a hellfire forge. Options!

Additionally, the middle ore gems from the Betweenlands are used for creating more complex Tinkers devices, and octine ingots are used for creating pistons (if you can't find any!).

Journey Map
A fair warning that the JourneyMap Token is extremely resource intensive. It requires the completion of all of the Twilight forest to obtain the Lamp of Cinders, as well as Charms of Keeping, which can only be found in Twilight Forest dungeon chests. The Ring of Ascent is only found in loot chests in the Betweenlands. If you're able to collect these pieces, the rest of the token should be easy peasy. Unlocking Journey Map will transfer all your location markers from the antique atlas, as well as reveal all the area you have ever visited prior to this point.

If you do not eat a JourneyMap Token in age 2 (medieval) or 3 (industrial), you will unlock advanced mapping automatically in age 4, the Modern Age. However, this will not count towards completion of the advancement (sorry, completionists).

Mobs
Endermen are the most notable mob that show up in the medieval age. They may spawn in any biome. Notably, two new dimensions become available, and all the mobs in them as well. These include the Betweenlands and Twilight Forest. Any mob capable of holding an item will now have 50% odds of an iron sword and 25% chance of a gold sword. All mobs capable of wearing armour have 50% odds of wearing iron armour, and 25% chance of gold armour. Additionally, all skeletons will now be equipped with bows, excepting trumpet skeletons.
