A new summon spell: summon lawyer.
While your attacking a monster, summon lawyer to sue them of their money!
You'll have little lawyer creatures running around, stealing money from monsters and adding it to your inventory. But the catch is that they also all lots of scrolls to your inv too!
... random half of which have to be signed to get the money permanently, and if you accidentally sign a wrong scroll you loose all your money, your appartaments, and still owe your pet lawyer money.
