Stat Boosting Rituals, Part 4 (Reduction)

Continuing from Stat Boosting Rituals, Part 1, 2, 3, … to discuss Perdo versions to reduce character attributes.

There is also a fair argument to say that as a Creo ritual can permanently increase the starts of a person, so to another Perdo spell could decrease their stats. As this is a baseline, the spell only has to be a ritual if it will be permanent, so temporary beneficial and punitive spells are also possible.

What isn’t clear is how the incremental base difficulties should work for Perdo based reductions. For Creo the base 30 increases any stat below 0 by +1, which is telling us that it is harder to raise higher stats. Likewise it is probably harder to make a very low stat worse than a higher one. There is also the Muto Corpus guidelines which imply that it is easier to shrink a target than grow.I could also see the logic of an argument which says the base should be the same, as it is affecting the body whole, but the same isn’t true for game mechanic reasons in Creo.

Overall I think it makes most sense (because it is a simplistic approach) to use the same guidelines as CrCo and CrMe for PeCo and PeMe except with -1 instead of +1 in the description.

For example, in Perdo Animal, Perdo Corpus, or Perdo Mentem :

  • Base 30 to reduce a stat by -1, on a stat which is equal to or less than 0.
  • Base 35 to reduce a stat by -1, on a stat which is equal to or less than 1.
  • Base 40 to reduce a stat by -1, on a stat which is equal to or less than 2.
  • Base 45 to reduce a stat by -1, on a stat which is equal to or less than 3.
  • Base 50 to reduce a stat by -1, on a stat which is equal to or less than 4.
  • Base 55 to reduce a stat by -1, on a stat which is equal to or less than 5.

Then as spell samples, although a level 60 ritual may as well just kill a person.

The Loss of Reason, Encircled

Perdo Mentem 35, R: Touch, D: Momentary, T: Circle, Ritual

Permanently decreases the affected targets Intelligence by 1 point, to a stat equal or less than 0.

The Withering of Reason, Encircled

Perdo Mentem 60, R: Touch, D: Momentary, T: Circle, Ritual

Permanently decreases the affected targets Intelligence by 1 point, to a stat equal or less than 5.

  1. Curious as to what your thoughts of stat boosting with Muto instead. Obviously we cant do permanent changes, and it would cause warping if ongoing long enough. But are there guidelines for the stat increases?

  2. I think it is similar to asking why Muto can’t temporarily heal, and it’s basically because it is more the domain of Creo than Muto. That said, a Muto spell can add to other stats like the way Gift of the Bear’s fort add to Soak. Perhaps Muto could gran the accelerated healing power or regenerative powers of some other creatures? Hmm.

  3. I definitely get that Creo is what governs moving a person towards their Ideal form. But Muto could give a person the strength of an ape or an ogre, could it not?
