I honestly do not think that there is a fully done baruna system done in any of the released sources. I think they are missing some stuff, but then again, good sir, I do not download most of the sources from the internets.
You can try to find a source that has the BarunaR2 define; however, I do not think that is actually the full baruna system either, good sir. So, you might end up with a conundrum, good sir.
