Jaws of Death

Jaws of Death is one of 's aura s in Xenoblade Chronicles. It heals him when he would otherwise be incapacitated, in addition to providing him with a boost to this talent gauge and physical arts damage.

Overview
Just like Reyn's, Jaws of Death's main use is to make Dunban not die when he otherwise would, such as by taking massive damage in a vision. The aura lasts long enough that timing it isn't too strict, but it does still have to be timed, or it will be lost - and its cooldown is long enough that it'll be a long time before he gets another chance. Unlike Last Stand, Jaws of Death also gains duration as it is upgraded, though it starts shorter to begin with.

A less-obvious use is to intentionally let Dunban's HP drain so he can use the aura and benefit from its healing, allowing the party to spend their healing arts elsewhere or wait for them to recharge. This sounds counterintuitive, but why heal Dunban for 25% when you can let him heal himself for 50% first? And since he also gains a boost to his offenses, this strategy pays off a lot more than doing the same for Reyn would.

Additional data
When the aura is triggered, it adds 50% to the party gauge and expires; it cannot be triggered more than once per use. It also adds 50% to Dunban's talent gauge and gives him Physical Arts Plus for 5 seconds.

There is a bug where triggering Jaws of Death in a vision sequence will still add 50% to the party gauge.
