Engage

Engage is one of 's aura Battle Arts in Xenoblade Chronicles. It attempts to apply Lock-On to the target, and if it succeeds, Mad Taunt generates 25% more aggro for the aura's duration.

Overview
Engage gives Reyn an out for when he can't get something's attention the old-fashioned way or he needs to do it very quickly. Ideally, he then uses Mad Taunt near the end of its duration so he can make best use of the extra aggro generated.
