Magics & Mechanics is a modpack about Magic (through Electroblob's Wizardry and Thaumcraft) and Machinery (Through Immersive Engineering and Nuclearcraft) with no questing system or main progression. Even though there's no concrete way to play it, here are some things you can do with it:
-Collect spells and research magical phenomena
-Make complicated machines and automate resource production
-Explore some cool dungeons and landscapes
-Make cool builds with Chisel blocks
-Get OP tools and weapons with a smeltery
-Kill and/or raise a dragon
And that's not the end of it! Who says you have to do anything from this list?
