Materials Checklist
First, you need to find his structure

You will know when you've found it. It's a big volcano in an ocean

Find a way inside the volcano. You won't need to break any blocks, just look around

You will need to look around this structure for heatstones. There will be a total of 8 and they look like the following images (all 8 are not shown.). Make sure you look everywhere. Mine all the ores, one is hidden behind some gold ore.
There is also a mega crystal somewhere in this maze.

Note: The room with the lava pool and dripstone has 2 heatstones and a secret barrel in the lava.
With a block of iron, you can now craft the Earth Core and summon Groudon

Using the Earth Core on the Groudon altar, you can summon him. Surprisingly, he will die to fire damage if you don't initiate a battle with him.

To get Primal Groudon, you will need to find the red orb. Fire resistance not only keeps you alive, but also helps you see. Dive straight into the lava and towards the bottom you can find the Red Orb.
