The non-weapon proficiency system in 2e was used in the Psionics Handbook to make psionics different from magic. A table demonstrated the number of powers a psionic character could know at any level. Each power was treated as a proficiency to determine success.
Since I make use of a similar system for psionic characters in my 2e inspired clone, I wanted to have other classes take advantage of a similar system. One example is the arcanist.
The arcanist is a part of the Wizard character group with some similarities with mages. Both have a written book to keep 'spells'. Both gain access to more powerful magic as they advance in levels. Both are very limited in the weaponry they employ. The biggest difference, however, is that the arcanist employs what I call arcane rituals to generate magic. A ritual consists of a glyph, rune, or shape combined with some kind of material component. For example, an aracanist would draw a line and sprinkle garlic powder onit to create a Protect from Undead spell. The glyphs and material components are up to the GM. I don't include them in this rough draft.
The pdf is thirty pages long, so I didn't post everything about it. You will notice that the rituals are about 95% composed of spells from the Labyrinth Lord Original Characters book. These were included to demonstrate a proof-of-concept more than anything. I added a couple spells, but in the final product the spells will be more carefully selected and defined.
Why Labyrinth Lord? I stated earlier that I didn't want to re-invent the wheel so I plan on using LL as a base. Hopefully the end result with be something similar to the Labyrinth Lord Advanced Edition Companion.
