Melter

The final step in the Age 0 progression is the "Let's Get Down and Melty" Advancement, which is a relatively simple advancement, as long as you've completed the prior ones.

You again have two options for the Melter: The Melter (it really should be called the Seared Melter) and the Porcelain Melter.

- The melter requires 6 Seared Bricks, one Flame Grilled Wopper, one Stone Grill, and one Primal Chest Advanced. Follow the steps you did previously for the seared bricks.

- The porcelain melter requires 6 Porcelain Bricks items, one Flame Grilled Wopper, one Stone Grill, and one Primal Chest Advanced. Follow the steps you did previously for the porcelain brick items.

The Primal Chest Advanced recipe is a multi-step upgrade process that starts with the basic Chest, which upgrades to a Primal Chest, and culminates in a Primal Chest Advanced. The recipes can be found in JEI.

Assemble the melter or porcelain melter according to JEI, and...boom! You're now in Age 1! Congratulations! :)
