These classes are written with the underlying philosophy that both players and GMs want to see PCs become interesting, unique actors in the world. They are designed as a negotiation, choose the most fun and cool abilities not the most powerful. These classes are designed with role playing goals or flavours which should colour their choices and actions in play. Recently Arnold K made a comment about PCs changing through play, because of their adventuring experiences. He succinctly summarised a tenet of play that has always been very important to me in making my PCs come to life. If you like these and use them or just get ideas and if any of them find their way to you table I'd love to hear what happened.
Pick a hit dice that seems fair or fits with your game or go with d8 or d6. There are no stat bonuses, penalties or minimum requirements assigned. This is by design. Let the PCs stats inform their actions and choices and form natural strengths and limitations within these bounds. But if stats floats your boats and you want something more defined consider where specialities and weakness lie in each class below and riff it.
"Each X levels", where X is a number of levels, will determine the rate of new powers gained. You may want to match these with the flavour/ power level of the other PCs in your game. Personally my preference is that Each X level = each level gained. Of course in the spirit of DIY feel free to take these concepts and flesh them out with more traditional class structure, tables etc.
Equipment is also not listed herein, with one notable exception, but many of these classes require special tools or accoutrements. It is assumed that PCs start the game with the basic tools, outfits or gear of their trade. Through adventure and questing they will likely gain more and useful objects and curios to help them in their pursuits of their chosen occupations. Refer to the above philosophy of collaboration if you have any questions about this.
