I have way too many ideas..
and i love the guilds im part of.. so
dont take these as anything more than suggestions

Racial specialization

Each scholor may decide to choose one player race as his area of expertise.
Depending on the amount of study marks in that particular race the character
has, he gains access to the skills,spells that are part of that particular
race. I wouldnt think anyhting thats directly related to a physiological
difference should be included...

and potentially the skills-spells are capped depending on the amount of study
marks for that race.
