Mictlan , how to play it effectively

[incognito]

How do you protect the vulnerabilites of a blood economy? Strikes me that it is damn easy to use unrest producing spells to make blood hunting difficult or kill off population en masse. Playing non-blood hunting races, I usually don't care about this issue, but here it really matters.

Certainly one method is a really 'deep' economy ie tons of blood hunting sites, but here you are just increasing tolerance for damage, not actually stopping it. Another method may be the virtual blood economy ie summons that in turn summon allies, soul contracts, special sites, etc that enable you to reap the fruits of blood income without the blood slaves coming in each turn. If you trace the turn-by-turn devil producing capacity back to the spell costs, you can generate a very high equivalent blood slave total this way given time. This is one reason I believe soul contracts are not imbalanced. They are necessary to balance the fragility of blood economies. What other ideas do people have?
