Here are some HPL style things I though up awile back.
Though they may not have much to do with your class I thought you might like them.

-StonefLesh:
Stoneflesh is the bane of all organic matrial in existance.
Any organic matrial (living, dead, or undead) that touches it is quickly consumed by it and
converted into more Stoneflesh. The Stoneflesh progressess at a rate of one inch per second. When the Stoneflesh
has consumed all of the organic matrial it is touching the organic being will, if not all ready, be dead.

If someone or something touches Stoneflesh the only way to save them is to cut off the area that is
being consumed, making certian to also cut off some of the surrounding flesh so as to ensure that you don't
leave any Stoneflesh as even the smallest amount is deadly. Attempting to pull or brush Stoneflesh off of
a person is NOT advised. Once Stoneflesh begins consuming matrial it does not cover a person then consume
their insides, but consumes their internal organic matrial at the same rate as the external matrial. So
pulling or brushing Stoneflesh will only serve to spread it more quickly.

If someone has gotten Stoneflesh on a vital section of their body (head, chest [i.e. heart, stomach, etc.],
etc) we suggest you cut off/out the Stoneflesh section and the surrounding flesh and then find a Cleric to
Raise them if they have died.

Destroying and transporting Stoneflesh is hard, but possible. Extreme heat such as that of a volcano
will destroy Stoneflesh. Summoning up Lave or Fire Elementals who are capable of creating such levels of
heat is a possible choice when choosing how to destroy Stoneflesh.

If you wish to transport Stoneflesh you must use a non-organic contianer to carry it. Boxes made of pure
stone, magical force, ice, etc. are your only choices as they are not organic. For maximum security make certian
that the stone flesh is completely surrounded by the non-organic matrial so that no flesh can fall in.

There is no save vs being consumed. This is a "die with no save" kind of substance so you are warned to
use it in your games VERY CAREFULLY! That in mind we hope you use it and have fun with it. :)

-Silver vien:
Any organic matrial that it touches will be slowly transformed into "something else". The process
takes several days. The new form of the creatures is almost always violent, omnivores, and mobile.

-Thought crystal:
Thought Crystal has a "thought smell" that most Otherworldly beings can not stand to be around. It has
been documented that some Otherworldly beings have even stopped hunting someone that has Thoughtstone on them.

-Black, Gold, and Clear crystal (Creature Gates):
A quasi-gate/demiplane/extrademinsional Space/portal toward some place/thing on this/another plane of existance. The things inside are similar to Devils in that they make deals with those who contact them. The price of a deal is never obvious to the person(s) making a deal with them. The deals
almost always seem free; this is unlikely, but no solid proof can be brought up to disprove that the gifts
are free.

The different crystals seem to contain/channel the same basic type of creature-thing. The primary differences are in how the creature-things "feel" and "sound" as they make a deal with someone. During a deal they seem to wash over a person as if the person is swimming in them. Black feels slick, chilly, and thick, Gold feels light, quick, and "deep," Clear seems to diffy proper discriptions even by the standards of the Otherworldly beings. The best description that can be gained is "warm."

The voices that the Creature-things use are also different for each crystal. The Black talk with a croking, gutural male voice that often reminds the more Elementaly educated of a cross between the croke of a toad and the voice of a Earth Elemental. The Gold talk with a happy female voice that giggles quite often. Listeners have described her as many different races as she seems to use the talking habits that the listener has. If the listener is speak in a very educated manner then so does the voice. The Clear crystal's voice follows much the same patteren as its "feel" in that no one can ever describe it well. In fact after talking with a Clear Crystal the listener never remembers what the voice sounded like or what they talked about. Only that they talked, it gave the listener something, and what that something is. These descriptions do not propperly prepar a person for how it "feels" and "sounds" to talk to these creature-things.
