FatalError's Adventure is a RPG based modpack with a difficult early game due to your level. Everyone starts at "level 0" and can level up through experience. When you level up you can apply points to your character attributes to build your ideal class from a classic MMORPG games. There are tons of bosses, structures, mobs, and adventure. Build your own colony for more content and have responsibilities as a leader to always have something to do. You'll find that a few vanilla mobs my be different from the rest, with more HP and abilities, they'll give you a run for your money. Even in full Diamond Armor, at level 0 is pretty difficult, due to your lack of experience making it to be slightly more realistic, "non pay to win game".
