I while ago I posted an Old School Essentials conversion for Dark Sun, one with many errors and typos that I am looking to fix with an update I am working on. However, right now I just finished the psionics part, in which I am presenting a new take on psionics rules for Old School Essentials and other OSR retroclones. The main goals here is to present a set of rules that is easy to read, remember and understand to use on the table. I hope you guys enjoy it and have fun with it!
In this document I include:
1 class (psionicist), rules for psionics powers using rank progression, optional rules for wild talents and a total of 42 powers that you can use and build characters with!
This is a work in progress, so please feel free to provide any feedback and correction you may find, thank you!
