Skills

Skills are the librarian's special abilities. Each skill has a Primary Principle and a Secondary Principle. Skills are used for exploring the Tree of Wisdoms (gaining new Soul cards in the process), Evolving existing Soul cards, Studying, and Crafting.

## Principles & Leveling Up

Each skill starts out with 2 of its Primary Principle and 1 of its Secondary Principle. Skills can be leveled up to have higher Principle values using Lessons, which can be acquired by studying books. When a skill is leveled up, each Principle is increased by 1. Level 9 is the maximum level for skills.

Upgrading a skill requires at least 1 Lesson. The total number of Lessons/Memories required corresponds to the next level of the skill (ex. upgrading a skill to lvl. 2 requires 1 Lesson and 1 Memory). Lessons/Memories are referred to as Understanding, and must match at least one of the skill's Principles. **The Lesson does not have to be of the same skill you are upgrading.** This also allows Languages to be upgraded, which are skills but do not have Lessons of their own.

## Soul Evolution

Evolving an Element of the Soul requires:

* A Skill attuned to that Element (obtained through attunement in the Tree of Wisdoms).
* Two of the same Element, at the same level.
* A Workstation matching both the Skill's Wisdom, and the Principles of the Skill/Element

What is important to note, is that it's recommended to **attune your Skill to an Element that matches (one of) its Principles.** This makes it easier to Evolve your Soul cards, as you only need to find a Workstation that matches the shared Principle (rather than two different Principles). See the Elements of the Soul page for more detailed information regarding Soul Evolution.

## Crafting

Certain Skills can be used for Crafting. Crafting can be done at any Workstation and has 3 challenge levels: Prentice, Scholar, and Keeper. To successfully craft something, one must use the correct skill and have a combined amount of 5 (Prentice), 10 (Scholar), or 15 (Keeper) power in one Principle. See the Crafting for more detailed information.

## Specialties

Some Skills have additional abilities, which can be used for removing Contamination from Books or for Crafting:

* Insects & Nectars
* Pyroglyphics
* Transformations & Liberations
* Meniscate Reflections
* Quenchings & Quellings
* Resurgences & Emergences
* Stitching & Binding
* Stone Stories
* Surgeries & Exsanguinations
* Sacra Solis Invicti
* Tridesma Hiera
* Maggephene Mysteries
* Purifications & Exaltations
* Sickle & Eclipse

## Languages

Languages are almost identical to regular Skills, with a couple exceptions:

* They are acquired through paying Visitors for a tutoring lesson.
* They do not have their own Lessons. Although relevant Lessons exist in the game files, there is no way to obtain them.
* Most importantly, they must be used as an 'extra' skill when reading Books written in Languages that the Librarian does not know by default.

As one only needs to use (a minimum of) one Lesson with matching Principles to upgrade a Skill, Languages can still be upgraded despite not having their own Lessons. Furthermore, Languages (just like regular skills) can be committed to the Tree of Wisdoms.

### Acquiring a Language

Languages can only be learnt from the random Visitors that appear each season (including Numa). Instead of speaking to them about any active event cards, the Librarian must "hire" them as a tutor, similar to hiring assistance from The Sweet Bones. Visitors must be paid in Spintria instead of regular currency. Doing so will begin a 3 minute timer at the end of which the visitor will leave, even if they came for an active event.
