Final Flicker

Final Flicker (, Backwater Shadow Technique) is one of 's support s in Xenoblade Chronicles. It allows Dunban to sacrifice a fifth of his max (rounded down) to fill half of his talent gauge.

Overview
Unlike with 's Battle Soul, Dunban generally does not find himself in situations where he suddenly needs access to his right away. But 20% of Dunban's max HP is not too great a loss compared to suddenly gaining ten s worth of talent gauge. It's probably not something Dunban will use whenever it's up, but if it's safe to lose the health, it's a potentially huge investment.
