Aura Burst (XC1)

Aura Burst is one of 's ether Battle Arts in Xenoblade Chronicles. It involves him slamming his weapon into the ground, causing a shockwave that deals damage to all nearby enemies, as well as lowering their physical strength. However, he can only use it when he has an aura active.

Overview
Aura Burst is a good tool for Reyn to take the attention of many enemies at once. Its damage isn't too good because it works off Reyn's party-worst ether stat, but it adds a good chunk of volatile aggro, and the strength-reducing effect means Reyn won't be losing quite as much from the upcoming attacks. Its main drawback is that it cannot just be used whenever, so if Reyn really wants to use it, he has to burn an aura at a perhaps inopportune time.
