User blog comment:ACWeapons/How much armor would RWBY characters need?/@comment-24891101-20151211164227

Other people have brought up Aura, but it's always good as a failsafe, so long as it doesn't impede mobility overmuch. Jaune and Pyrrha look good, and it makes sense, since neither is particularly acrobatic. Ren looks good except the shoulders, since they impede mobility too much. The rest of his looks fine. Coco is approximately unarmored.
