[Pyramid #3/66] Safe Thresholds for Ritual Symbols

Celti · 05-27-2015, 01:35 AM

A player in one of my games wants to use Ritual Symbols for his RPM caster. I'm allowing it, it's reasonably balanced from what I can see (we'll find out!).

However, one of the things that Ritual Symbols changes is that you suffer a -1 penalty to energy gathering rolls on every fifth attempt, instead of every third. This blows the Safe Threshold table all to hell and I can't figure out how to reverse engineer the formulas. The energy for effective skills 13, 14, 16, and 17 roughly matches up to three dead-average (10.5) energy-gathering rolls (or five for 17, as befits it for the -1 penalty not reducing chance of failure). None of the other numbers match up, however.

Given that my programming skills outweigh my maths here and the game starts tomorrow evening, I'm just going to write a calculator that does all the rolling automagically and ignore the quick-and-dirty charms rules for now, but the perfectionist in me demands an answer.

Any ideas?
