Counter Vial is a Vial-based counter Trinket that turns a healing risk into a counterattack. When Mina is struck while readying a Vial, Counter Vial dodges the hit and fires a burst back at the attacker. This guide covers where to buy it, when Lady Susan stocks it, how the counter timing works, and how it compares with other Vial Trinkets like Plasma Funnel and Intravenous Vial.
Quick Answer
Counter Vial is a Vial-based counter Trinket sold by Lady Susan at Ossex Trinket Bazaar after the shop expands. Public trinket lists report it as a 2,000 Bones purchase. Its effect triggers when Mina is struck while readying a Vial: she dodges the hit and launches a burst back at the attacker, making it useful for players who want to turn risky healing windows into counterattacks.

Counter Vial Location
Counter Vial is found in Ossex. It is sold by Lady Susan at the Trinket Bazaar — the large Trinket shop near the central Ossex fountain. It is not a chest reward, boss drop, or quest reward based on current public sources.
For the full area layout, see the Ossex Map.
When Does Lady Susan Sell Counter Vial?
Counter Vial is not listed as an early Bazaar item in public trinket lists. It appears after the Trinket Bazaar expands — a stock upgrade that happens as the story progresses.
Some public sources place this expansion after defeating the Bone Beach boss. If Counter Vial is not in Lady Susan's stock yet, progress the story further and check the Trinket Bazaar again after Bone Beach progression or the next major story milestone.
How Much Does Counter Vial Cost?
Public trinket lists report Counter Vial as a 2,000 Bones purchase. This makes it a mid-range shop Trinket — more expensive than early Bazaar items but less costly than some late-game purchases.
If you are short on Bones, consider:
- Farming Bones with Deboning Wand and Stolenoid
- Selling unneeded Trinkets at Pawnty's Exchange
- Progressing further and returning with more Bones later
Counter Vial Effect Explained
Counter Vial's effect triggers only during a Vial-readying window:
Dodge and launch a burst at the attacker if struck while readying a Vial.
This is not a passive shield or automatic defense. Counter Vial only matters when Mina is actively readying a Vial — that is, when the player is holding the heal input. If an enemy attack lands during that window, Counter Vial dodges the hit and fires a burst back at the attacker.
This makes Counter Vial fundamentally different from:
- Passive defense Trinkets that reduce damage automatically
- Intravenous Vial which auto-heals without player input
- Dodging Pendulum which triggers on a timed Jump press, not a heal input
Counter Vial rewards players who understand enemy attack timing and can predict when to start a heal. It punishes enemies for interrupting Mina at her most vulnerable moment.
How to Use Counter Vial
Treat Counter Vial as a risky heal-window counter. The basic flow is:
- An enemy telegraphs an attack.
- Start readying a Vial just before the hit lands.
- If timed correctly, Counter Vial dodges the hit and fires a burst at the attacker.
Key usage notes:
- If timing is off, Mina may still get hit and the Vial may be interrupted without the counter triggering.
- Counter Vial is not automatic safety. It depends on reading enemy attacks and deliberately starting a heal at the right moment.
- Multi-enemy rooms are riskier. Overlapping attacks or projectiles can hit Mina between counter windows.
- It works best against predictable, single-hit enemies before graduating to boss patterns.
Do not treat Counter Vial as a replacement for basic dodging and positioning. It is an additional layer of counterplay, not a substitute for movement.
Counter Vial vs Other Vial Trinkets
Counter Vial is one of several Trinkets tied to Vial use and healing. Here is how it compares:
| Trinket | What It Does | Best For |
|---|---|---|
| Counter Vial | Dodges and counters if struck while readying a Vial | Reactive counterplay during heal windows |
| Plasma Funnel | Drinks Plasma Vials faster; helps prevent losing Vials when hit | Safer, faster healing |
| Intravenous Vial | Automatically uses a Vial without drinking when Plasma is available | Passive emergency healing |
| Vial Salvo | Launches missiles when using a Vial; bonus Plasma if hits land | Offensive Vial use |
| Primed Vial Pouch | Carries 2 extra Plasma Vials; Vials always restore some health | More Vial capacity |
| Valor Medallion | Move while healing; no Plasma lost when struck | Safer heal positioning |
Each Trinket solves a different problem. Counter Vial is the only one that turns a healing window into a counterattack. Plasma Funnel and Intravenous Vial focus on making healing safer and more automatic. Vial Salvo adds offensive power to Vial use. Primed Vial Pouch and Valor Medallion expand capacity and positioning.
Is Counter Vial Worth Buying?
Yes, for players who often get punished while healing or want a more aggressive Vial-based defense. At 2,000 Bones, it is a reasonable investment if the playstyle fits.
Counter Vial is strong when:
- You understand enemy attack timing and can predict when hits will land
- You frequently get interrupted while trying to heal
- You want to turn defensive moments into counterattacks
- You are practicing boss patterns and want a safety net during heal attempts
Counter Vial is weaker when:
- You prefer simple, always-on defensive Trinkets
- You rarely use manual Vial healing
- You have not yet built up enough Vial economy to support frequent heal attempts
- You are fighting in chaotic multi-enemy rooms where timing is hard to control
If you just want safer, more reliable healing, Plasma Funnel or Intravenous Vial may be better choices. If you want to weaponize your healing windows, Counter Vial is the pick.

Best Builds for Counter Vial
Counter Vial fits Vial-focused builds and timing-based counterplay styles. It works best when you have enough Vial capacity and Vial support to make frequent heal attempts viable.
Trinkets that complement Counter Vial in Vial-heavy setups:
- Primed Vial Pouch — More Vials means more opportunities to use Vial-related effects, including Counter Vial's counter window.
- Valor Medallion — Moving while healing and keeping Plasma when struck make the heal-window counterplay more forgiving.
- Plasma Funnel — Faster Vial drinking reduces the window where Mina is vulnerable, which pairs naturally with Counter Vial's counter timing.
- Vial Salvo — Another Vial-triggered offensive option. Some players enjoy stacking multiple Vial effects for heal-window offense.
Trinkets for comparison (different use case):
- Intravenous Vial — Automatic healing instead of manual counter timing. Different approach, same Vial theme.
- Dodging Pendulum — Another timing-based defensive Trinket, but triggered by Jump instead of Vial-readying.
Some players report enjoying Counter Vial in Vial-heavy setups with Trinkets like Valor Medallion and Primed Vial Pouch, but treat those as build ideas rather than mandatory pairings.
Common Mistakes
- Expecting Counter Vial to work as a passive shield. It only triggers when Mina is actively readying a Vial and gets hit. It does not provide any protection outside that window.
- Trying to use it without readying a Vial. The effect is tied to the Vial-readying action. If you are not holding the heal input, Counter Vial does nothing.
- Buying it before having enough Vial economy to support it. If you only have 1-2 Plasma Vials and rarely use them, Counter Vial offers limited value.
- Using it in chaotic multi-enemy rooms before learning the timing. Start with predictable single-enemy encounters to get comfortable with the counter window.
- Assuming it replaces basic dodging or positioning. Counter Vial is a supplement, not a substitute, for movement and spacing.
- Confusing it with Intravenous Vial or Plasma Funnel. Counter Vial does not make healing faster or automatic — it adds a counterattack when you get hit while healing.

No. It is tied to readying a Vial. It is not a passive shield and should not be treated as automatic damage prevention.
Is Counter Vial good?
Counter Vial is good for players who understand enemy timing and want to turn risky healing windows into counterattacks. It is less useful if the player wants simple passive defense.
Is Counter Vial better than Plasma Funnel?
They solve different problems. Counter Vial turns a risky Vial-readying moment into a counter, while Plasma Funnel makes Vial drinking faster and safer. Use Counter Vial for reactive counterplay and Plasma Funnel for more reliable healing comfort.
Is Counter Vial better than Intravenous Vial?
They are different. Intravenous Vial is more passive because it automatically uses a Vial when enough Plasma is available. Counter Vial is more timing-based because it triggers when Mina is hit while readying a Vial.
