Auric testla is one of the things needed to make Omega alloy, that means that Xander would essentially have a part of Omega alloy in his armor. Auric testla armor is also the second strongest melee armor in the multiverse, The melee Auric testla armor would also make the Muramasa/Muramase way stronger than it would be in cosmilite. Auric testla armor also provides the user with an insane dash. Auric testla armor is also the fourth strongest armor (it is beaten by Omega ankh armor, Omega alloy armor, and Eggyhead's shell)
