hmmm, could use a little boost perhaps. Immunity to entangle so far if I remember the recipe I wrote. Maybe also a little tumble bonus to represent being able to walk on walls and leap from precariously strange positions in combat? I tried to base them off the wall walking ones in the DMG, though I still havent seen the stats on them IG. Bioware gives us some pretty confounding limitations. (like the game engine never truly designed for wall-walking)
Send me a PM on what they do now in game and the components/skill level needed for them and I'll try to figure some things out for a variant recipe.
