There is some confusion here on how Puissant (Ability) affects the cost to increase a skill by a level.
Our multi-lingual scholar Zephyrum (an early fan of Fibonacci's translation of Hindu-arabic numbers) has both Affinity with (Artes Liberales) and Puissant (Artes Liberales), and at character creation spent 50 points on Artes Liberales.
The way we interpreted it, this would mean a score of 4 in the ability, the Affinity would raise the score to 5, and then Puissant would effectively bump the score up to 7.
Now Zephyrum is studying to increase his score in Artes Liberales, and we are undecided if the advancement cost should be based on the number of points already invested in Artes Liberales (ie score 5), or include the Puissant Ability (ie score 7).
Can anyone clarify please?
One of the arguments being thrown about is - Can a character have a (latent) Virtue Puissant (Ability) before learning that Ability?
Though the the bit about "writing" does suggest its own question.
Zephyrum's score in Artes Liberales is the number of different alphabets he can read. Should it be 5 or 7?
