Dominus Gladiatus Herb: What It Does and How to Get One

In Dominus Gladiatus, an herb removes one injury from a gladiator, and you obtain it by hiring the ventor and sending gladiators out on expeditions beyond the Ludus. The in-game description calls the ventor "a seasoned hunter" who "leads gladiators beyond the Ludus in search of herbs, remedies, and rare supplies," and warns that "what they return with is never certain."

What an herb does

The herb is a consumable with one stated effect: remove one injury. Injuries come from fatigue above five, from arena fights, and they carry penalties such as slower training, so an herb is essentially a portable cure. It mattered in one recorded run precisely because a gladiator was already being treated in the Infirmary when the herb arrived, making it redundant at that moment — so check who is actually injured before you send an expedition, and time the run so the herb lands while the injury is still untreated.

The Infirmary remains the main treatment route: it costs gold to build and a per-use fee, and each injury takes about two days of treatment. An herb is the alternative when you would rather not pay or wait.

How to get an herb: hire a ventor and send expeditions

1. Hire the ventor

   He appears among the hireable staff, described as a seasoned hunter who leads gladiators beyond the Ludus in search of herbs, remedies and rare supplies. Budget for both his hiring price and your running upkeep, since the Ludus charges rent daily.

2. Send a gladiator out

   With the ventor hired, you can launch a scavenging run that sends one of your gladiators into the wild to gather consumables. Any available gladiator can go, so many players keep one dedicated to repeated runs.

3. Wait for the return

   The gladiator comes back after the run ends with a random haul. Observed finds include an herb (remove one injury), an animal hide (sellable for coins), an apple (a damage boost) and a cabbage (a morale increase).

4. Use or store the herb

   Apply it to an injured gladiator to clear one injury immediately, or hold it for the next injury that a fight or fatigue causes.

One player noted a wait of roughly three days before the same gladiator could be sent out again, and that keeping someone on permanent scavenging duty felt strong enough to justify it. Treat that cooldown as that player's observation rather than a documented number.

Check note

The herb effect, the ventor's description, the possible expedition returns and the cooldown observation come from a first-hand full-release playthrough video; the ventor mechanic itself is new to the full release, not the October demo. Game basics such as the Infirmary cross-check with the official Steam page. Exact expedition odds and the precise cooldown length remain unconfirmed.
