I'll include ranged/thrown weapon mindblade as an ACF.
I origanlly planned on there being a way to invest essentia into the mind blade but it must of have been lost during the making. The plan was to increase the damage die and possibly provide a bonus to combat maneuvers that you can use your mindblade allows you to perform(like a trip bonus if your minblade was a spiked chain). Any other thoughts for possible ideas for essentia in the mindblade?
Also the word "soulknife' only appers in the profiency area as far as I can tell.
edit: added knife to the soul and essentia blade
