(school x) Specialization Staff (two handed magical staff, very powerful items or artefacts, level 7-8 in a school, 1 version for each school) : the specialization staves are only usefull to a mage proficient in several schools of magic. When wielding a Specialization Staff he looses his powers in all schools but the one of the staff, but his proficiency in this one is greatly increased. (magic bonus : 1 point for the first point he had in other schools, + 1 for two more total levels in other schools, +1 for 4 more levels, +1 for 8 more, etc... - ie : a fire 3 water 3 astral 2 earth 2 mage carrying a fire specialization staff will become a fire 6 mage ; a fire 3 astral 10 earth 5 with the same staff will become a fire 7 mage)

Shouldn't a level be added at levels 1, 3(+2), 6(+3), and 10(+4) in other schools? Then it fits evenly into 10, otherwise it maxes out at 7, after granting 3 more levels. An alternative is making it use 1, 4(+3), and 10(+6).

I like your ideas, very interesting!
