How to Get Rain Man in Once Human: Locations and Farming Tips

To get Rain Man in Once Human, you need to defeat Rainfall Reapers, elite enemies that can drop it as a Deviation. It isn't a guaranteed drop, so expect to farm them a few times. Rain Man is a territory Deviant that boosts your crops and waters them for you, which makes it one of the best Deviants for farming. Here's where to find Rainfall Reapers and how to farm the drop quickly.

Rain Man at a glance

Where do you find Rain Man in Once Human?

Rain Man drops from Rainfall Reapers. The two spawns most guides agree on are both in Broken Delta:

• Harborside: on the docks, next to a partly beached ship, with other Deviated enemies around her.
• Sutherland Chemical Plant: on the catwalks around the central blue building.

Some guides list extra spawns elsewhere, such as inside the Seepage Zone at Securement Silo Phi and the Greywater Industrial Zone in Iron River. Map coordinates vary slightly between guides, so look for her near those landmarks.

How do you farm Rain Man?

Rain Man is a random drop, so you might need several kills. To speed it up:

• Wait for the respawn: elite enemies in the open world respawn after a while (guides put it at around 15 minutes).
• Change worlds: after a kill, use the teleporter or a Worldstone to switch to another world and check the same spot again for another Rainfall Reaper.
• Relog at a safe spot: some players log out for a minute or two and log back in to reset nearby enemies.
• Come prepared: Rainfall Reapers are elites with good loot, so bring decent gear and ammo.

What does Rain Man do?

Rain Man's ability, "Hoping for a Downpour", increases the vitality of your crops and waters them automatically, so you need fewer irrigation systems in your territory. The more Deviant Energy it has, the bigger the boost. It's useful in both PvE and PvP servers.

How do you use Rain Man in your territory?

1. Build an Isolated Securement Unit in your territory.
2. Place Rain Man in it to activate it.
3. Keep it happy: Rain Man likes blue light (Circular Lights, unlocked through Basic Furniture II under Building) and a Fridge nearby (unlocked through Refrigeration under Logistics). Both speed up its Power and Mood regeneration.

Is Once Human still getting updates?

Yes. Starry Studio keeps updating Once Human regularly. The latest update, version 3.0.7 on September 28, 2026, made character reshaping free and added the Golden Autumn event, and the 3.0.6 update in September strengthened biomechanical units, including the Rainfall Reaper.
