Inventions (Soul Society Supplement)

Inventions

While most people focus on the fighting prowess of the warriors, the work of the mind is also astonishingly useful in the spiritual world. The most creative geniuses have created diverse inventions that could be used both for good and for evil.

Creating Inventions

To create an invention, there are some things one must have in mind. The first is its proficiencies needed, which comes from your ability to invent said object. The second being its rarity, with it defining the difficulty of creating such a resource. The third is its needed materials, the things that will fill your invention. And the fourth is its creation time, defining how long such a process will take.

After meeting all prerequisites, you must make an Intelligence (Arcana) check. On a failure, you fail to create the invention and lose half of the raw materials used. On a success, you create the invention successfully.

Proficiencies

To create something complex, you must first understand its basics. You must be proficient with tools related to the object you are trying to create (typically artisan's tools), and must also be using said tools during its creation.

Invention Rarity

There are four rarities when it comes to inventions; Average, Rare, Unique and Revolutionary. The DC for creating an invention depends on its rarity. See the DC table below for details:

DC Table

Rarity	DC
Average	15
Rare	20
Unique	25
Revolutionary	30

Materials

Inventions need raw materials when being created. All inventions specify a GP worth of raw materials needed to create it.

Creation Time

Creating takes time, most of the time it takes a very long time. The duration of an invention depends on its complexity rather than its rarity.

Shikai Ability Modification

Prerequisites: Must have a Zanpakuto with a Shikai and Bankai and must be 11th level.

You're able to modify your shikai to bring out stronger effects, allowing it to be more effective. During a long rest, you may spend 100 gp and 15 reiryoku to enhance one Shikai feature your zanpakuto has. Work with your DM to decide what part of the feature to modify and bring out greater effects. An example would be modifying Ashisogi Jizō’s Ashi hakaimono effect to be stronger, making them only begin making the save to escape the effects at the end of their turns instead of at the beginning of their turns.

Zanpakuto Remodel

During a long rest, you may spend 400 gp and 50 reiryoku to remodel your zanpakuto, allowing it to be “never properly fixed” but keep the original strength of its effects. When your zanpakuto is destroyed in bankai form and you choose to remodel it, you no longer create weaker effects and keep the same features for as long as you choose to remodel and not have it properly fixed.

Bankai Destruction

Zanpakuto destroyed in bankai, it can never be returned to its former state, resulting in the bankai being weaker. Work with your DM to figure out what features of your Bankai become weaker.

Bankai Ability Modification

Prerequisites: Must have a Zanpakuto with a Shikai and Bankai and must be 18th level.

You've reached the pinnacle of bonding with your zanpakuto such as how you've reached the pinnacle of zanpakuto modification, now being able to modify even your Bankai.

An example of a new bankai feature would be Ashisogi Jizo’s Bankai, Konjiki Ashisogi Jizō, would gain the ability to generate modified Ashisogi Jizō based on the information you've gathered to counter the ability of your opponents, such as generating nerves all over its body which have 70,000 layers that peep off whenever something would enter its body, making it immune to the The Compulsory schrift’s features.
