Limitation for "requires human sacrifice"?
 

Let's say I'm creating a summon demon spell as an "Ally always available, summonable, minion, unusual powers" and I want to put a limitation that it requires a human sacrifice (illegal, risky, etc.) What would be the limitation's value? Would the price reduction come after figureing the total cost of the summons? If not, it would hardly have any effect since the "summonable" alone is +100%.

Trigger (Rare, Illegal, -60%) along with Preparation Required (1 hour, -50%).

Humans usually aren't rare.

But human sacrifices are not usually something you can simply find or buy, they must be arranged. On B115 that counts as Rare.

Nor are humans necessarily protected by law, depending on the local government, and/or if slavery is allowed.

Okay, I suppose I should have asked if this was a setting where you could pop down to the corner store and ask the chemist for a quick human sacrifice whenever you need it.

The OP says that human sacrifice is illegal and risky. I am pretty sure we can assume we are talking about a setting that is more like medieval Europe than an industrial Aztec empire.

If the campaign is using Multiplicative Modifiers, the enhancements and limitations are tallied separately and applied sequentially. For example, an Ally Group with a base cost of [100] cp, with Summonable (+100%), Trigger (-60%) and Preparation Required (-50%) would cost 100*(1+1.0)*(1-0.8), or [40] cp. Remember that the maximum limitation value is -80%, whether using the normal ("additive") modifier scheme or multiplicative. Using the standard Additive Modifiers, it would cost 100*(1+1.0-1.1), or [90] cp.

Thank you. This helps a lot.

If you use Multiplicative Modifiers you need to use them for every ability in the game. The rules aren't balanced for being able to use either method at will.
