Mad Taunt (XC1)

Mad Taunt is 's in Xenoblade Chronicles. It has him taunt the target enemy, creating a huge spike in aggro that degrades over 30 seconds. If used again within that time, the total aggro generated will be added together and degrade at the same rate.

Overview
Mad Taunt generates an order of magnitude more aggro than most other arts, making it Reyn's best way of grabbing attention from others. Due to how the math works with overlapping usages of it, it's best to use as often as possible, which lasts for the same total time as a "just as the previous one runs out" strategy but confers an equal or higher total aggro over the full duration. Therefore, there is little reason to hold it once Reyn has it, unless the target will soon die or the plan is to save the talent gauge for Magnum Charge.
