Is There a Costs Money Limitation?

[Musk]

Hey guys,

We're in the process of moving one of our fantasy games to GURPS. We're going to use powers to model magic spells. For some spells, we'll require pretty expensive material components.(1000$ and up). I was wondering if there was a limitiation somewhere I could use to model this. (-x% per y $)

In Powers, they did mention a -10% for material components but that's for your run of the mill components.

One example of a spell would be a raise dead spell where you need to make a significant offering to your god... (sort of like how in D&D 3rd it costs 5000$ for a raise dead).

Thanks!

Maybe Trigger?

I think there may be one or two writeups, out there, although probably unofficial, using the expensive Paut potion (normally used to regain FP for spellcasting) as a Trigger Limtation.

You can use Requires Preparation, with material offerings being the preparation needed. If you have a nice stockpile of stuff, you just have to put the right things in the right places, otherwise, it's time to go buy/find/steal what you need.

Otherwise, use a Trigger limitation for the materials required.

You could kludge something together from Trading Points For Money (p. B26). Each character point spent gives you 10% of Average Campaign Starting Wealth, if you reverse "Costs Character Points" and use the 5x multiplier that means such a advantage might give you 10% of Starting Wealth for 5 points. So maybe -5% per 10% of Starting Wealth (or -1% per 2%).

This sounds good to me and I would not adjust based on individual starting wealth.
Costs FP is not adjusted for extra FP, ER or FP regeneration which all could be handled with extra starting wealth.

Thanks!! That's exactly what I needed.

I use this in a TL3 game; scale appropriately for higher TL:

-10% for a material component that nominally costs a buck, but can be scrounged or made.
-10% more per order of magnitude more expensive: -20% for $10, -30% for $100.
+20% for an item that's not consumed, e.g., net -20% for a $1000 wand or holy symbol
