Exploration

Abandoned Cities

Some buildings are haunted. The monsters that spawn in haunted buildings can spawn quickly and run very fast. These mobs also have really good armor and a lot of health. Explore with caution. In case you thought that was it, some mobs have guns and they hurt if you are not armored well. Thanks to HardcoreDarkness, darkness is real. Carry many torches.

Villagers

Find a village and look for a resident that can trade with you for items from the ActuallyAdditions mod. A book is provided at the start, read it.

Ore Samples

Mark locations of found ore samples in Journey Map. It will help you get the resources you'll need later.

Distance

Finally, some mobs will get harder the further you wander from original spawn. You have been warned.
