'''Villagers''' are entities added by vanilla Minecraft that spawn in [[Village]]s during world generation. GTNH adds both new villager types and new trades for existing villagers. Not only are villagesthey a good source of hard to acquire resources in the early game, some villagers will offer trades that are quite profitable. The Heretic and Wizard villagers are key to [https://docs.google.com/document/d/1VF9HJPsaJasY_V_3OeJOX5RIRzGx5Xjfr-iBzzjfZGU/edit Stone Age Thaumcraft] progression, Priests sell Eye of Ender that normally requires a HV Chemical Bath to make, Lumberjack and Apiarist villages can jumpstart tree or bee breeding. A group of protected villagers can also be turned into a passive Emerald farm as they will periodically shed emeralds which can be collected with item logistics, such as a Vacuum Hopper.
== Profitable Trades ==
In terms of easiest emerald generation, Farmers are by far the best villager to use. Most of their trades are buys, in contrast to most other villagers who have few, if any. The downside is that Farmers want a large variety of Pam's Harvestcraft crops. An extensive farm is needed to effectively generate emeralds using Farmers. The other benefit of levelling up Farmer(s) is access to a variety of Pam's fruit tree saplings, including some that are necessary for the [[Healing Axe]] quest. Another income option is to set up a passive Emerald farm by placing penned villagers near a Vacuum Hopper or other dropped item collection system. While slow, this requires no player interaction.
The blacksmithBlacksmith is also notable for potentially lucrative trades, involving certus quartz/dust and raw silicon. The variance of potential trade values is very high. With some luck, a blacksmith will offer a good rate of exchange that results in profit when sold back to the same blacksmith or another. Due to the other trades being quite expensive, Blacksmiths are best levelled after securing a steady supply of emeralds. Other easy trades include raw meat to the Butcher, and Ignoble Princess bees to the Apiarist. Paper is a less attractive option in GTNH due to the difficulty of early production, unless Paperbark trees are usedfarmed or for [[MV]]+ players.
The Priest and Heretic both offer access to early glowstone - less valuable in this pack due to the Glowflower > Extractor recipe, but potentially helpful for players who haven't found a Glowflower to farm yet. The Priest also has redstone at a very high cost, but which might be worthwhile for a player trying to make an [[Ore Finder Wand]]. The Librarian has renewable glass and several items for progression in Hardcore Ender Expansion. The Wizard villager sells light sources, a renewable way of getting Mana Beans, and a much easier to afford Purifying Bath Salts source for novice Thaumaturges. Knowledge Fragments are expensive but give 1-2 of each primal [[Thaumcraft Tips#Research|research]] for Stone Age Thaumcraft runs where the Thaumometer isn't available yet.
