Algarithms: (Yithian Psionic Technology):
Unlike normal Psionics that are an internal power to be manipulated, this recovered Yithian science allows the Artificer to manipulate external ambient psionics to perform minor scientific tasks. This may appear to be a form of
Sorcery and due to it's ancient alien methods, may be a branch off of ancient sorceries. For all intents and purposes treat Algarithms as psionics for use in resisting and disrupting. Such powers are developed by the Artificer by over time and experience imprinting Yithian Algarithms discovered in ancient ruins, crystals and sacred scientific tablets.
This can eventually manifest as strange circuit like patterns and other oddities. (This is like the Sorcerer's Corruptions that form over time and power.)
Aside from Artificers, the following other groups might have access to these abilities: Yithians, Grey Space Aliens, Reclaimers, Gods of Law, etc...
Unlike standard Psionics, these abilities might be usable by the cold logical Space Aliens without risk of emotions and insanity developing.

Formulae (Alchemical Potions & Scientific Experiments):
In "Realms of Crawling Chaos" (by Daniel Proctor and Michael Curtist and produced by Goblinoid Games) Formulae were added. Much like the descriptions for spells and rituals, except in that book they were the alchemical creations of Sorcerers. Hyadian Schism uses this as well. Any listing of Formulae from that book will be in name only and not link any information as it is intended as reference only. Players should look into that book for details on such Formulae.
All described Formulae are new creations not present within that book.
In my game I have the new Formulae fit under different categories:
*[Any]: Anyone competent enough in alchemy can attempt to create the Formulae described
*[Artificer]: Only an Artificer (Mad Scientist) or other class with high technical skills can attempt to make this Formulae. Also known as blue prints for Formulae referring to object/mechanism creation.
*[Sorcerer]: Only a Sorcerer can attempt to create the Formulae. Perhaps a specific ritual aspect is included in the Formulae that must be performed in order for the ingredients to activate/cooperate properly...

Gizmos:
These are simple single purpose items created by Artificers. They will have a small number of charges and are not permanent.
Think along the lines of 60's Batman Utility belt items.
