Applied Energistics 2

This is our first released version for 1.19. We don't expect world-breaking bugs, but exert caution and make sure to report any issue you might encounter. The API for addon developers should already be stable, with a few maintenance changes from the 1.18.2 API.

Please note that certus quartz was reworked heavily, and the wiki might not be up-to-date yet. Here is a summary of the changes:

Removed certus/fluix seeds and certus quartz ore

Self-explanatory. See below for the replacements.

Budding certus quartz

Budding certus quartz is a new block that will grow certus quartz crystals, similar to how budding amethyst grows amethyst shards. It exists in the following variants:

• Flawless: will never deplete. Breaking with silk touch gives Flawed, breaking without silk touch gives a regular Certus Quartz Block.
• Flawed: has a 1/12 chance to deplete to Chipped after growing a crystal. Breaking with silk touch gives Chipped, breaking without silk touch gives a regular Certus Quartz Block.
• Chipped: has a 1/12 chance to deplete to Damaged after growing a crystal. Breaking with silk touch gives Damaged, breaking without silk touch gives a regular Certus Quartz Block.
• Damaged: has a 1/12 chance to deplete to regular Certus Quartz Block. Breaking always gives a regular Certus Quartz Block.

Flawless is a lot easier to automate because it doesn't need replacement (see below), however it can only be moved by using Spatial IO or other modded block moving techniques (e.g. Create contraptions).

Left to right: Flawless, Flawed, Chipped, Damaged, regular block.

Certus quartz buds

They exist in 3 growth stages. Breaking them with silk touch gives the bud itself, breaking without silk touch gives certus quartz dust.

Certus quartz clusters

The 4th and final growth stage. Breaking them with silk touch gives the cluster itself, breaking without silk touch gives 4 certus quartz crystals, increased by fortune.

Recharging budding certus quartz

A "depleted" certus quartz block can be recharged using charged certus quartz:

• Certus Quartz Block + Charged Certus Quartz -> Damaged Budding Certus Quartz,
• Damaged Budding Certus Quartz + Charged Certus Quartz -> Chipped Budding Certus Quartz,
• Chipped Quartz Block + Charged Certus Quartz -> Flawed Budding Certus Quartz,
• (Flawless Budding Certus Quartz is not craftable, it can only be found in meteorites).

In order:

Meteorite changes

Meteorites now contain a small room around the chest containing a few Certus Quartz Blocks (either the regular one, or one of the 4 budding variants, picked randomly), and a few buds. Fluix blocks have been removed.

Since obtaining certus quartz requires finding a meteorite, the meteorite compass is now crafted by charging a regular compass in the Charger.

Crystal growth accelerators

CGAs will now increase the random tick rate of adjacent blocks tagged with #ae2:growth_acceleratable. By default this only includes budding amethyst and the 4 budding certus quartz, but packmakers can configure this tag to support any tag. The acceleration rate is configurable.

Example automation setup with 4 budding blocks (requires additional autocrafting to turn the depleted blocks back into their flawless variant):

Turning certus and fluix dust back into crystals

This is now possible using charged certus quartz in water:

In-world crafting for fluix now gives fluix crystals (as was the case in 1.16-).
