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.
