I want to play TDE again after more than 15 years. I need some help gauging things plausibly. TDE 4.1 has a rule for how much you can increase an ability. I believe it is
highest involved attribute + 3
Personally, I tend to be far away from this threshold. I also take care to stay below 15, as the game says that 15 is master level.
That being said, I wonder what thresholds to apply. I will give you a short background story.
I am generating an albino magician with fear of light who was abandoned by his mother - a Zahori courtesan - in Elenvina. He was found by a Travia priest and given to an old couple that raised him, not knowing of his magical potential. He would often help in the garden or gather herbs in the comfortably dark forest. His foster mother would then sell them to an alchemist.
When very pressed he would unknowingly perform healing (balsam) to counteract the constant damage in sunlight and horriphobus to scare the other children that were beating him.
One day, when his foster mother was ill, he found a valuable plant (Alraune) and wanted to exchange it for a cure at the alchemist's. But the alchemist cursed him and kept the plant. He tried to steal an elixir and was caught by the very stern white magician Ruane of Elenvina, who happened to be shopping. She scared him so much that he unconciously performed horriphobus, uncovering his potential. White magicians are required by the rules to make sure such children are educated. Given the boy's non existant means , she could not send him elsewhere. So he was admitted to the Academy in Elenvina.
Because of his story I gave the boy a special talent for balsam and horriphobus. I also want him to be very skilled in these. How far can I raise his horriphobus skill, considering that horriphobus is a house spell (Hauszauber) in Elenvina and all adepts there have a strong horriphobus (+6) by default? All adepts also have special skill in the branch (Merkmal) "influence" of this spell.
How far could I raise balsam? He practices it a lot to replenish LeP from albinism, but it is not an Elenvina speciality (+2 by default) and Healing is not an Elenvina speciality either.
What about spells like Ignifaxius that don't have the appropriate characteristic "influence" and are taught strongly by default in Elenvina (+4), but which he does not use too frequently?
What about completely random, but known spells like dublicatus?
I will play him very defensively, but like anyone who has been other people's punching bag long enough, he could also value fighting (staves, ignifaxius) more than noble born colleagues. How much may I raise staves?
EDIT: an other point is that horriphobus only tests my excellent abilities. Practically it will make little difference if I set it to 10 or 13. But lore-wise it would be nice. If I don't put the points into horriphobus I have limited options. Herbalist skills and things a magician can learn. Probably my character would end up stronger rather than weaker. I already invested quite a bit in languages. I can make it work nicely lorewise. He is curious about his tulamidic origins and invested quite a bit into tulamidic and ancient tulamidic.
