an aura while teleporting... interesting choice of words, anyhow an eth steel carapace is good for barbs pallys mercs or any melee sort vs another melee class usually but in certain specifics its not, to the right person its worth lots, i dunno the exact price but i would estimate aprox 1/4 to 1/2 of a perf one since the def is a lil below average (for its type)
