It's a cheat skill since spells never meant to be cast on yourself become slef-castable and it doesn't require gaming knowledge to take advantage of that fact.
An actual curse would be that his mana pool is actually his bank account.
And anytime he casts a spell he lose money based on it's level and mana cost, and going into debt reduces his Intelligence. So after a certain point he becomes both debt-ridden and retarded.
