Blade Lineage Mercenary doesn't have health regeneration.
But.
His Domain Expansion.
Swordplay of the Homeland, states that upon using your skills into a varying order, you gain Poise up to twenty.
Poise increases your skills Crit Chances, making Mercenary immortal by killing everything.
During the run, Don Quickscope Railgunner asked:
Who would win? You or the prisonner of the Moon ring?
Mercenary answered:
If I landed Yield My Flesh, it might cause me a little trouble.
[Don Quickscope Railgunner]
But would you lose?
Nah, I'd lose.

Roland Gangnam style.
