Herobrine Mod, an extension made by Trittering Walk with Tynker. This mod adds a brand new crafting ingredient to the game, called "combustible coil". This ingredient is used as fuel for the generator that produces power in the "Forge". I found out that you can also craft armor with this new material.
This mod uses a very easy to understand interface, and its really great for those who want to make their own mods. Just follow the instructions inside the mod folder and you will be able to get started immediately. There are many other mods that use the same technology as Herobrine Mod. One of them is the Tox Bombers addon, which uses the same concept of generating mobs at a strategic location and then summoning them at a distance using a furnace. It also integrates with the "forge" mod.
This is one of my favorite mods, since I love both the concept and the implementation of it. When I started playing this game I wasn't too sure about how I would level up, since the XP rewards seemed very small and didn't give me enough incentive. After playing with HeroBrine for a while, I started getting more XP from quests and from kills so I started using the HeroBrine mod to increase the XP rewards from quests and kill. It turned out that the combination of both the HeroBrine mod and the heat mechanic in HeroBrine enabled me to make the most of the limited XP and that's why I like both the heroine mod and heat mechanic from this game.
