GloomCraft

A hard modpack that has a very interesting twist on survival that makes it so you burn in the sun. This mod fits both for those who like exploring, those who like fighting mobs and bosses as well as those who like building and farming.

The main mods in this modpack are:
Burn in the sun, Mystical agriculture, chickens, techguns, sky orchards, projectE, avaritia and projectEX

The mod also contains blood magic, good night's sleep and deep mob learning but those are not the main mods

In total there are 151 carefully picked mods

Your goal is to make a base as quickly as possible in order to not get burned by the sun and then get resources from the many resource mods so that you have a chance to beat the numerous hard mobs outside. After this you simply keep progressing and you can choose your own end goal, like infinity armor from avaritia or the final star from projectEX.
