Dungeon looting, collectables collecting and adventuring in different dimensions when you are ready for the challenge. End goal: collect everything!
It's a relatively easy modpack as you can get really nice gear early on and build your arsenal from there. Try to find one of the roguelike dungeon buildings, hopefully the house in the forrest and get the loot from upstairs and then head down to the first floor. That should get you a decent iron sword and some armour. if you find the smelting room make sure to pick up the anvil as you'll be able to enchant your tools with the books you find on the first floor. Head out once you are satisfied with your first looting expedition and search for a battletower. The cave spiders are a pain so take out the other spawner and kill some until you get the bauble they drop which makes you immune to poison. THEN KEEP LOOTING!
