This is a followup to the D&D.Sci post I made twelve days ago; if you haven’t already read it, you should do so now before spoiling yourself.

Here is the web interactive I built to let you evaluate your solution; below is an explanation of the rules used to generate the dataset (my full generation code is available here, in case you’re curious about details I omitted). You’ll probably want to test your answer before reading any further.

Ruleset

(Note: to make writing this easier, I’m using standard D&D dice notation, in which “3+4d8” means “roll four eight-sided dice, sum the results, then add three”.)

Ghost Generation

Traits

Ghosts have nine traits which can affect the price of an exorcism: Intellect, Corporeality, Sliminess, Hostility, Grotesqueness, Deviousness, Perversity, Paradoxicality, and Unholiness, each a positive integer with a max of 100. Of these, the PPEK only measures the first five.

For the typical ghost (kind of; see next section), these traits are generated per the below table:

Trait	Generator
Intellect	1d80 + min(1d20, 1d20)
Corporeality	1d60 + 1d20 + min(1d20, 1d20)
Sliminess	[Corporeality]/5 + 1d60 + min(1d20, 1d20)
Hostility	1d80 + min(1d10, 1d10) + 1d10
Grotesqueness	min(1d20, [Hostility]/5) + [Corporeality]/10 + 1d10 + 1d60
Deviousness	[Intellect]/10 + 1d10 + 1d80
Perversity	1d60 + min(1d40, 1d40)
Paradoxicality	1d100
Unholiness	1d60 + 1d40

Categories

A ghost is either a Wisp, Spirit, or Horror. Wisps, when generating each trait, roll three times and pick the lowest result; Spirits roll once; Horrors roll three times and pick the highest.

43.3% of ghosts are Wisps, 19.3% are Spirits, and 37.4% are Horrors.

Exorcism Prices

The cost of an exorcism varies randomly in a triangular distribution from 50% to 150% of the mean.

Phantom Pummelers

The Pummelers, as the name suggests, tend to solve problems with their fists. They are aided slightly by Corporeality (they have ways to drag enemies into the physical plane, but find life somewhat simpler when they get to skip that step), hindered greatly by Sliminess, and impeded by Perversity and Unholiness.

E (P P) = 610 - 6 * c o r p + 41 * s l i m + 12 * p e r v + 8 * u n h o

Wraith Wranglers

The Wranglers believe in talking things out, seeing their task as gently helping ghosts to pass on. Their ideal client has high Intellect, low Deviousness, low Paradoxicality, and - most importantly - low Hostility.

E (W W) = 521 - 5 * i n t e + 39 * h o s t + 15 * d e v i + 17 * p a r a
