This "delta" class was designed to fit in with systems like B/X where there is still some slow form of advancement, and the cost of certain moves reflect that. If circumstances should make a requirement cheaper, that's absolutely fine. It was also designed with a "normal" campaign in mind, where a party of multiple PCs are going on adventures and delving into dungeon spaces together, so progressing along the path of the Conjurer is intended to dovetail into normal activities and into the downtime and management of gradually leveling D&D characters, as well as provide a few mysteries to unravel. The class is meant to try to "solve" some issues that can come up with delta advancement while inventing a satisfactory martial delta class. It does so by leaning into the numinous quality of fictional martial arts. Treat Adverse Conjuring moves as being magical in nature, and all that that implies.
This is a way of living and a way of killing. It is most often practiced by the destitute, the damaged, and the desperate, but being rich is no excuse. Adverse Conjuring is the art of perceiving something's purpose and reversing it. The purpose of a human being is to create life and nurture it.
The fighting moves of Adverse Conjuring cannot be done with a sword, unless it is a very strange sword. They can be done with the body. They can be done with a weapon descended from a tool— a flail, a knife, a warhammer, a staff.
Basic moves can be learned by any journeyman who is initiated into Adverse Conjuring. Specialist moves can be learned by any Conjurer who is taught by a mentor. Chaperon moves can be learned by any Conjurer who teaches others. Immortal moves are shrouded in mystery.
