Yeah I cannot remember the exact build, but we were rolling 5th level characters, and I chose whatever I needed to have both dual wielded kukri and the ability to shadowjump. The tattoos used a rule in one of the 3.5 supplements where you could purchase a magic item but alter it's physical description... so I took something that altered his armor class, but instead of being a ring or a glove or whatever it was the DM allowed me to make it rune tattoos.
