About this project
What does Ars Affinity add?
A progression system for Ars Nouveau that tracks player affinity with different spell schools and provides passive effects based on experience. You can also have 1 active effect at a time, such as 'Swap' from the school of Manipulation or 'Dash' from Air.
Progression
Ars Affinity adds a new screen showing your progress in each spell school. As you cast spells, you gain affinity with that school, unlocking new points to allocate perks in that school. Progressing more in a school means it gets harder to progress further in others, i.e. specialization is encouraged, but it is technically possible to get every perk, with a lot of patience.

Perks

Every school provides Resistance and Power perks. Power perks increase your spell power within a school, while resistance gives you resistance against spells in that school. Other than that, every school has unique passive perks and each have an active ability perk as well.
Please see the live docs for a full overview of perks.
