Here's another big project of mine I've gotten around to getting to a stage I feel it's worth sharing: Prestige Classes!
A key inspiration behind the design of this system was the 3.5e system of having prestige classes that would have as features say '+1 level to existing arcane spellcasting class'. For my modernization of this, I've simplified it from having dozens of different categorisations for classes, and given each PrC the feature 'Core Class Advancement', which advances a select feature from each class.
The core design philosophy for this was to make it so each prestige class was available for the majority of classes in the game at some stage. Rather than PrC's in 3.5e that often only worked for one or two classes, this aims to have each PrC apply to most classes.
As such, the amount of customizability each PrC offers should be pretty high, as the intended design of this was to multiply the number of possible character archetypes you could play.
But yeah, Core Class Advancement stands as my solution to the issues raised by wizards of the coast's abandoned UA for prestige classes: often times, taking a PrC means you don't get the cool stuff from your own class. But with this, even if it's delayed, you still get progression in your core features.
I hope the prestige classes I've made are fun to look at
Oh yeah, people asked for a PDF of the last big post I made, so here's a link to the shareable homebrewery version of the doc
