The fastest way to level your Deviations in Once Human’s Deviation: Secure, Capture, and Preserve scenario is by capturing Digby Boys to obtain Exp Aggregators, crafting Exp Aggregators yourself, while farming EXP from defeating enemies in the field serves as a slower, secondary option.

![]() Locate Digby Boys Digby Boys can spawn in various areas, but the most reliable spot to catch them is the Lv. 9 Gym in the Blackfell Area (Coordinates: 5741, -1726). |
| 2 |
Capture Digby Boys Capture Digby Boys using a Binding Grenade. Sometimes they disguise themselves as ores that shuffle around, so watch closely! The more Digby Boys you snag, the more Exp Aggregators they'll bring back over time. ▶︎ How to Capture Deviations in Deviation: SCP Scenario |
| 3 |
Assign Them to Securement Units Place captured Digby Boys into Securement Units from your Symbiosis menu. Once assigned, they’ll automatically start retrieving Exp Aggregators I, II, and III for you, with higher-level Digby Boys fetching better rewards. |
| 4 |
![]() Collect Exp Aggregators Regularly Check back often to claim the Exp Aggregators your Digby Boys have gathered. Unlike crafting, this method is passive and keeps producing while you explore or fight elsewhere. Tip: The more Digby Boys you capture and assign, the faster your Aggregator stockpile grows. |
| # | Step by Step Objectives |
|---|---|
| 1 |
![]() Learn Exp Aggregator Memetic I Open your Memetic screen and unlock Exp Aggregator memetic under the Crafting tab. This allows you to craft Exp Aggregators. The Exp Aggregator is exclusive to the Deviation: SCP scenario, meaning it can only be obtained and used within this scenario. |
| 2 |
![]() Craft Exp Aggregator at the Supplies Workbench Once you’ve unlocked the memetic, build a Primary Supplies Workbench and craft an Exp Aggregator, which costs 1 Combat Memory (dropped from enemies in this scenario), 3 Electronic Parts, 5 Adhesives, and 1 Waste Plastic. |
| 3 |
![]() Go to Symbiosis and Click Upgrade Level Click Upgrade Level in the Symbiosis screen. Despite what the text description says, Exp Aggregator is actually a consumable that instantly grants EXP to your Deviations - just go to Symbiosis and click Upgrade Level to use it. |
| 4 |
Craft Many Exp Aggregators You can also choose how many Exp Aggregators to use when leveling up a Deviation, making it easy to boost their levels quickly if needed. Craft as many Exp Aggregators as you can to speed up your Deviations’ leveling. Once you progress further, you’ll unlock Exp Aggregator II and III, which grant even more EXP to your Deviations. To farm materials fast, revisit enemy-dense zones and repeatable encounters that drop Combat Memories, loot corpses and nearby containers/supply caches, and run those hotspots repeatedly so you can craft as many Aggregators as possible. |

You can also gain EXP by defeating enemies and other Deviations in the field with your own team, but this method is not as efficient compared to using Exp Aggregators.
Still, you’ll need to travel across different locations to gather the materials for crafting Exp Aggregators, which also means defeating the enemies that drop Combat Memory.
