Beast of Reincarnation Cleanse Walker Upgrade Guide: Memory Chips and Skull Material Location

Bauera, the Cleanse Walker, is your mobile base in Beast of Reincarnation. Its upgrade tracks feed into weapon upgrade tiers, research, cooking support, duplication, and facility growth, so it is not just a rest stop between missions.

Cleanse Walker upgrades raise Bauera’s core systems

Upgrading the Cleanse Walker means raising Bauera’s Power, Calculations, and Knowledge ranks. These ranks gate the systems that make your exploration loop stronger, including further weapon enhancement, item research, ranged/projectile improvements, spirit stone duplication, cooking recipes, and other base-side progression.

You will still use campsites for several character and weapon tasks, but Cleanse Walker rank upgrades are cashed in at Bauera. That is why returning to the Walker regularly matters: it turns materials you found in the field into new upgrade access instead of letting them sit in your inventory.

Cleanse Walker materials and their uses

The three skull-shaped materials are color-coded around Bauera’s main stats. Treat Facility Modules as a separate category, because they do not raise Power, Calculations, or Knowledge directly.

Match the material to the stat you want to improve instead of dumping everything into one screen blindly. The colors are the easiest way to remember it: green for Knowledge, blue for Power, and orange for Calculations.

How to upgrade cleanse walker in Beast of Reincarnation

Collect skull materials

Open Strongboxes and check beside defunct Rusted Golems while exploring for Memory Chips, Generator Devices, and Electronic Brains.

Return to the Cleanse Walker

Go back to Bauera, because these rank upgrades are cashed in at the Walker rather than from a campsite.

Open the upgrade interface

Use Bauera’s upgrade or abilities interface; exact prompt labels can vary by platform, so look for the Cleanse Walker stat screen.

Spend the matching material

Put Memory Chips into Knowledge, Generator Devices into Power, and Electronic Brains into Calculations.

Check new access

After raising a rank, look over newly available perks, research options, recipes, duplication access, or weapon upgrade tiers before heading back out.

Strongboxes and Rusted Golems are the main material sources

The most reliable pattern is to check Strongboxes and the areas around defunct Rusted Golems. Strongboxes work like timed input chests: activate one, hit the prompted directions before the timer runs out, and claim the reward inside.

Memory Chips, Generator Devices, and Electronic Brains appear as skull-shaped items, so they stand out from common loot once you know what you are looking for. Exact farming routes and drop rates are not fixed enough to build around here, so the practical habit is to clear interactable boxes and inspect Rusted Golem spots as you naturally push through zones.

Power, Calculations, and Knowledge unlock different perks

Each Cleanse Walker stat supports a different part of progression. If a system feels capped, check which Bauera rank it depends on before spending more field resources elsewhere.

This is why a blocked weapon upgrade is often a Cleanse Walker problem rather than an amber problem. If the weapon menu stops at an early tier, Bauera may need more Power or Knowledge before that weapon line can advance further.

Facility Modules upgrade Bauera’s base facilities

Facility Modules belong to the Cleanse Walker upgrade loop, but they work differently from skull materials. Instead of raising one of the three rank stats, they expand life-support and base facilities inside Bauera.

The main examples are the Incubator and Grow Chamber. These facilities support food production for Kagura, whose cooking gives permanent stat buffs, so facility upgrades are indirect character growth rather than a purely cosmetic base improvement.

The Incubator starts with limited egg capacity, and modules expand that side of the system over time. Capacity details can be a little uneven between chicken slots and total Fertilized Eggs, so plan around the useful part: more facility investment means more support for Kagura’s meals.

Early Cleanse Walker upgrade priorities

Early on, spend skull materials as soon as you can turn them into a real rank increase. Power is the cleanest priority when weapon caps are holding back combat progress, because higher weapon tiers have an immediate effect on fights.

Pick Knowledge earlier if you are leaning into research, ranged weapons, projectile damage, quiver improvements, or bow upgrades. Once cooking is available, start feeding Facility Modules into food-related facilities so Kagura’s permanent meal buffs begin stacking sooner.

Cleanse Walker mistakes that slow progression

The biggest mistake is carrying skull materials for too long. They are meant to be converted into Bauera ranks early and often, not saved while your weapons, research, and base systems stay capped.

Also avoid mixing up the color tracks: blue goes to Power, orange goes to Calculations, and green goes to Knowledge. Finally, do not ignore Facility Modules just because they do not look as direct as weapon upgrades; better food facilities feed into permanent stat growth through Kagura’s cooking.
