In my First Civilization's Legacy Series, spell casters require aptitude and training, especially to advance.
As they advance, they begin to take on 'aspects' of their craft. Seers begin to lose their physical sight, Enchanters become more and more susceptible to magic used against them, sorcerers become more physically twisted and disabled, healers become unable to harm others, necromancers...well, not pretty, etc.
This sounds very written and artificial. Having different drawbacks that seem tailor made to each class.
