What is in it

Built to give you a bit of everything

Big technical projects, proper magic, nicer building, better multiplayer quality of life, and admin support that is not an afterthought.

Automate everything

Conveyor belts, ore processing, digital storage, routed items, autocrafting, and enough machinery to turn a hillside into a mildly alarming production line.

Spells and rituals

Write your own spells, brew trouble in a cauldron, raise altars, and fly about on a broom because walking is beneath you now.

Build something lovely

More block variants, better furniture, cleaner industrial pieces, and enough decorative choice to stop every base becoming a cobblestone cube.

Get playing quickly

Up and running in about two minutes

No scavenger hunt for jar files. No manual mod wrangling. Just import the pack and let the launcher get on with it.

1

Grab the pack

Hit the download button above. You will get a small .mrpack file rather than a giant zip full of mods.

2

Import it

Open Prism Launcher, choose Add Instance, then Import, and point it at the file.

3

Play

Launch the instance and let it fetch what it needs. After the first run, it behaves like any other instance.
