Finally, I made all the wisdom branches at 9. To do this, I calculated which skills should be in what place. I took into account connections between branches, because there are 81 slots for skills, but only 73 skills (including languages).
This is not an optimal placement, I think someone can make a better tree. I tried to take into account the benefits of each skill when using it for crafting. Language skills that are on slots 1 and 2 can be swapped on their branch.





Some skills deserve better placements, and I'm not entirely sure about the balance of getting Elements of the Soul to level them up.

** - Transformations & Liberations and Glaziery & Lightsmithing swapped places, unlike the image, because I found out that Transformations & Liberations are more useful in crafting, but already installed it on the Tree of Wisdom.

Building a tree with languages in the first slots is made because they are not used in crafting. However, it can be long and tedious due to the fact that there are few Elements of the Soul at the beginning and you need Spintria to get the language skill. This way you can use skills from the second or third level on the first if you got them quickly. This will speed up the start of the game.

Learn new skills as soon as you acquire them. You'll use them later anyway. Also use lessons to improve your skills whenever possible. Don't wait for the Numa season, after which all the lessons will be burned.

If you feel like you've raised a skill too high, but haven't put it on the Tree of Wisdom yet, use Consider with Element of the Soul during the Numa season. This will reduce the skill to 1 and will give lessons in the number of lessons/memories used to improve it. But keep in mind the possibility of consuming lessons before the end of the season.

Don't rush to evolve the Elements of Soul. The more Elements you have, the more actions you can take during the day. This is especially valuable in Numa when rare rewards are available.
