Crucible
The Crucible is the primary crafting station and interaction point of the mod. It is essential to work with Powers, is the host to all Reactions, and performs many special case behaviors.
To create a Crucible, craft a Cauldron and place it in the world. Then, craft a Scroll of Transmutation (any of the three recipes will work equally well) and use the Scroll on the Cauldron.
Before the Crucible is useful, it must be filled with water. This can be done using any Forge fluid compatible item container, such as the vanilla Water Bucket. There's no need to heat it once filled.
If you wish to empty the Crucible, shift-right-click with an empty hand. This will void any Power inside. Some kind of Power cause effects in the surrounding area when emptied, which can be dangerous, so be careful!
Item entities inside the Crucible are periodically checked and processed. If you don't want to throw items in manually, any kind of automatic insertion (e.g. Hoppers) will drop items as entities inside the Crucible for you. If the item matches any of the 'power'_sources tags, it will be dissolved and a small amount of the corresponding power will be added to the Crucible. Associations between items and these tags are not shown in game unless you enable the showPowerSources client config option.
The amount of Power for each item is world-specific, but falls within one of two ranges.
| Tag Status | Yield Range (Percent of Crucible) |
|---|---|
No high_potency tag |
2.5% to 15.6% |
Tagged high_potency
|
5.6% to 31.3% |
Some items are the inputs to recipes. See JEI or the Journal for a list of these recipes. The only hidden information for these comes from Transmutation recipes, which each have a hidden minimum total amount of relevant Power that must be met for the recipe to work, even if you add the right item to the right combination of Powers.
Also, keep in mind that there are allowed to be Powers besides those listed in the recipe. For example, if a recipe requires Blaze, and the Crucible contains both Blaze and Body, the presence of Body will not prevent the recipe from working.
Crucibles occasionally scan the world around them for particular objects, which they then memorize. These objects can cause the Crucible to do things like gather Power or unlock new kinds of Reactions, and are sometimes required by Objects of Study. See Area Memory for a complete summary.
Depending on the mixture of Powers in a Crucible and the status of its area memory, different Reactions may occur. These range between beneficial effect, the creation of new Powers, and hazardous phenomena. See Reactions for a complete summary.
The Crucible responds to Redstone, and provides comparator output. However, this is not as simple as you might believe.
If a strong input signal is above (world specific; 11 - 14), it will cause one of three (world specific) outcomes:
- The Crucible's Power content is voided, but the water remains.
- The Crucible's Power content is severely reduced.
- The Crucible reacts as if it had been shift-right-clicked.
Comparator output follows this formula (but you might be better served by testing it in your world empirically):
- If the Integrity is below 85%, output 0.
- If the Crucible is linked to an Ender Crystal, output 15.
- Set the signal to 1 if the Crucible is full of water.
- Add a number from 0 to (world specific; 4 - 12) depending on the amount of total Power.
- Add (world specific; 1 - 7) if the Crucible is charged.
- Add a fluctuating amount if the Crucible has an ender rift inside it.
Integrity is the measure of how well the Crucible's internal magical structure is functioning.
A Corrupt Cell below the Crucible is currently the only way its integrity can decrease.
Integrity starts at 100, and decreases every few ticks (based on a configurable value) that a Corrupt Cell remains below the Crucible. Until integrity 10, if the Corrupt Cell is removed, the Crucible will gradually recover.
| Integrity Threshold | Effect |
|---|---|
| 85 | Integrity violation; comparator output falls to 0. |
| 70 | Crucible looses the ability to process items and starts slowly voiding Power. |
| 50 | A ring of runes becomes visible around the Crucible. |
| 20 | A humming sound is audible. |
| 10 | Crucible can no longer recover. Final cascade begins. |
| 0 | Crucible reverts to a Cauldron. |
