How-To: Variable (Uncontrollable) Fatigue Cost?
I was peeking at some Shadowrun material the other day, and realized part of what I miss from its magic system under GURPS: the uncertainty a mage has about what the exact price will be (in fatigue or health loss) for casting a spell.
Now, GURPS seems to be quite devoted to fixed and knowable costs: you can fiddle with whether a power activates (such as with Fickle or Unreliable), and you can scale how strongly a power works (via Variable), but I haven't seen any method for assessing random costs given a constant "output." I've looked at Backlash, but it only enforces conditions or basic-characteristic penalties on the user. I suppose what I'm looking for is some way to link an attack, directed at the user, upon any use of the power -- but I don't see a way to do that using the rules as written. Any suggestions from the GURPS gurus out there? |

For a power, I'd just make "1d FP cost" worth -15% and make "2d FP cost" worth -35%, the same as for 3 FP and 7 FP, respectively.

Variable fatigue cost with an average cost of N points should be worth a slightly larger limitation than a fixed fatigue cost of N.

(It also enables the user to try, with a < 50% chance of success, to use it in circumstances where, with a fixed cost of the average, it would not work, but this is less of a benefit than the cost of uncertainty.) |
