So, to summarize: these are selectable as Feats/menu options, and each one gives a single ability. If you have multiple, you get increasing numbers of combinations, and there are some longer combinations that can only be learned as quest rewards. It kinda reminds me of Illumian sigils, though expanded a fair bit.

I like this idea in theory, and I think that you have made an interesting variety of options, but I will need to take a closer look at the execution, and see what specific suggestions I can give. I'll write up a detailed response in a few hours, after I get home form work.
