There are few items that boost many paths at once. Staves of Elemental Mastery, Rings of Wizardy, Rings of Sorcery... and Robe of the Magi. However, the last one has nasty side-effect of imposing Horror Mark on its wielder. I think it is of stronger kind than that imposed by the spell.

Ok, newbie question here: is there a way to boost a pretender's level in a magic *school* (not path) after gamestart?

Thanks, it's probably a really basic question...but I am just starting out...
