Joule Syringe
Quick Answer: Joule Syringe
Joule Syringe is a Utility Trinket in Mina the Hollower that changes how Mina's Sidearms interact with Plasma, Joules, and health. Sidearm attacks generate Plasma unless Mina is at 1 HP.
When Mina has no Joules remaining, Joule Syringe allows her to continue using Sidearms by spending health instead. The Trinket is found inside a treasure chest in Bone Beach.

How Does Joule Syringe Work?
Joule Syringe reroutes part of Mina's Sidearm resource economy. While Mina has more than 1 HP, using Sidearms helps generate Plasma, making the Trinket useful for builds that fire Sidearms frequently.
If Mina reaches 0 Joules, she can still activate a Sidearm, but the attack consumes health instead. This gives the player more offensive options after running out of Joules, but it can also place Mina in immediate danger.
Plasma generation stops when Mina reaches 1 HP, preventing the Trinket from creating a completely safe resource loop at critical health.
Is Joule Syringe Worth Using?
Joule Syringe is worth using in a Sidearm-focused build. It rewards players who frequently use ranged attacks and understand how to manage Joules, Plasma, and health as connected resources.
Its main advantage is flexibility. Mina can generate Plasma through active Sidearm use and can continue attacking even after her Joules have been depleted.
Its weakness is risk. Spending health at 0 Joules can turn a small resource mistake into a death, especially during bosses or crowded combat rooms.
Best Uses for Joule Syringe
- Sidearm-focused combat builds.
- Generating additional Plasma while using Sidearms.
- Continuing to fire after reaching 0 Joules.
- Aggressive boss strategies that rely on frequent ranged attacks.
- Players who can closely manage health and avoid accidental health-consuming attacks.
Joule Syringe Build Tips
- Watch your Joule counter before repeatedly activating a Sidearm.
- Avoid spending health accidentally when Mina is already close to death.
- Use the Plasma generation effect while Mina remains safely above 1 HP.
- Pair Joule Syringe with a Sidearm that you can use consistently without placing Mina in unsafe positions.
- Treat the 0-Joule health cost as an emergency option rather than unlimited free ammunition.
