Purity is bought from the Ancient Golem Merchant in the Ancient Civilization Zone for 4,390 Amber, and its Vampiric Blade effect lets Emma heal from damage dealt on hit.
Purity is an early sustain katana for players who want to recover HP while damaging enemies instead of relying only on dodging. You can pick it up during the Chapter 2 route toward the power supplies/generators, near the robot mech at the rest/fast-travel point.

Vampiric Blade heals on hit
KEY!
The important correction is simple: Purity heals when you damage enemies. Its healing comes from Vampiric Blade, which restores HP on hit based on damage dealt, not after a successful sword parry.
Emma’s attacks restore HP based on the damage she deals. That makes Purity reward steady offense: keep landing hits, keep pressure on the enemy, and use the returned HP to stay in the fight longer.
Attack consistently to trigger Vampiric Blade healing on hit; bigger damage means more HP returned while you keep pressure on the enemy.
Purity upgrade scaling and best use
| Upgrade | Effect |
|---|---|
| Base Purity | 27 melee attack; Vampiric Blade restores 3.5% of damage dealt |
| Purity +1 | 34 melee attack; restores 5% of damage dealt for 5 seconds |
| Further upgrades shown | Healing value rises to 6.5%, then 8.5% |
Purity is strongest when you want sustain more than raw damage. It helps a lot in boss fights where you can stay aggressive, keep landing hits, and turn your damage into healing instead of constantly backing off.
That makes Purity a strong early sustain weapon and a useful boss-learning pick. It is not automatically your best late-game DPS option, so keep upgrading it while the healing is carrying fights, then compare later swords once raw damage and stronger effects start to matter more.
About the Pilgrim’s Zone merchant claim
Some players point to a Chapter 3 Pilgrim’s Zone location, sold by a Wandering Merchant near Nushi’s Lair Entrance. Use the Chapter 2 Ancient Civilization Zone route above as your first plan, since it gets you to the Ancient Golem Merchant stock earlier and lines up with the generator objective.
Bell Sword and parry-build choices after Purity
After Purity, the natural comparison is Bell Sword and other early-game swords built around close-range play. If you like Purity’s sustain loop, also look at broader katana choices such as Purifier Blade before spending too many upgrade materials on one weapon.
The decision is less about chasing a universal tier list and more about what your fights need right now. Stay with Purity when healing is saving runs; move on when a later sword gives your build better damage, safer pressure, or a stronger special effect.

Frequently Asked Questions
Does Purity heal on every hit without parrying?
Yes. Vampiric Blade restores HP on hit based on damage dealt, not from a successful sword parry.
Is Purity good for boss fights?
Yes. Bosses give repeated chances to keep attacking, so Purity can turn steady damage into HP recovery while you maintain pressure.
Should you keep upgrading Purity into the late game?
Upgrade it while the sustain is helping you win fights, then reassess when later swords start giving better damage or effects for your build.
