Beast of Reincarnation First Region Best Route – Weapons and Upgrades

Beast of Reincarnation rewards players who treat the first region as a gear sweep instead of a straight boss rush. The route below is built around fast, nearby pickups that immediately improve Emma’s ranged options, Koo’s support value, survivability, and parry-based damage.

How to obtain all items in first region of Beast of Reincarnation

The clean route is a west-to-north sweep: grab the western ammo manual first, use camps to decode and reset, then cross the river for the second facility before spending story progress to reach the lake tower and riverside building. This is a practical early power route, not a full-game walkthrough.

Combat habits before the gear sweep

Use vines as part of combat, not just travel. Holding the jump from vines gives Emma enough height to cross gaps, reset spacing, and line up drop attacks before enemies have time to settle into their attack patterns.

Start hard fights from above whenever the arena allows it. A stealth drop assassination can remove a large chunk of health from early shield users and Heavy Golem enemies, which turns long trades into short stagger windows.

Once the fight is active, parry instead of only dodging away. Parries build stagger, trigger weapon effects, and give Koo time to land shield-break or stagger support against tougher enemies.

How to take the early power route in Beast of Reincarnation

Start from the opening area, sweep west for arrows and a charm, then climb north through the river route for armor, skills, and the Mechblade (Light).

Check the west-and-north route

From the starting map, set your path toward the western Fire Arrows facility, the northern river facility, the lake tower, and the riverside building.

Loot the Unidentified Charm

Enter the small tent west of the start and grab the charm before pushing into the nearby facility.

Pick up nine Fire Arrows

Open the chest inside the western facility so Emma has Fire Arrows before crafting support comes online.

Learn Manual: Fire Arrows

Take Manual: Fire Arrows from the facility table after looting the arrows.

Decode the charm at camp

Rest at a camp altar to decode the charm into a Koo charm, then equip the result.

Ask the Keeper Golem for locations

Choose its weapon or recipe dialogue to mark the Mechblade (Light) or Acid Bolts location on the map.

Ambush the Heavy Golem by the second facility

Open with a drop assassination, then parry through the fight while Koo helps build stagger.

Open the nearby strongbox

Use code 08110 and take the consumables, Walker upgrade items, and Koo support loot inside.

Equip Recovery Tonic (S) on Koo

Put Recovery Tonic (S) in Koo’s slot so he can add healing during the next fights.

Cross north over the river

Use vines and rooftops to reach the second facility without taking the slower direct approach.

Drop onto the facility guard

Avoid the elevator approach, take the cliff above the enemy, and begin with another assassination.

Collect Acid Bolts and the manual

Pick up the loose Acid Bolts, then take Manual: Acid Bolts from the nearby table.

Activate the lower camp

Use the camp below the boss arena as your close respawn point before repeating the encounter or pushing upward.

Spend points toward Helm Spliter

Put early Emma points into Vitality and unlock Helm Spliter for a heavy aerial stagger attack.

Follow story progress to the first subcity

Resume the main objective until the route opens toward the lake tower and riverside building.

Climb to the second tower campsite

Cross the nearby gap and reach the campsite and strongbox above the lake path.

Take Chain Mail from the strongbox

Loot Chain Mail from the tower strongbox and equip it before the next climb.

Scale the riverside building

Use grappling points and vines to climb the tallest building in the area.

Activate the camp below the top fight

Rest at the camp just under the encounter so a failed attempt restarts close by.

Equip boss tools before the climb

Slot Acid Bolts, unlock Helm Spliter, and equip the armor and Koo support you found.

Approach from behind the boss

Skip the stairs, jump behind the target, and begin the fight with a drop assassination.

Burn the boss with Acid Bolts

Use Acid Bolts to apply damage over time and weaken its armor while parries and Koo pressure keep stagger moving.

Claim Mechblade (Light)

Open the chest inside the upper structure and equip Mechblade (Light) as your early parry-focused weapon.

Early pickup payoffs

This route works because it changes several early fights at once. Ammo manuals make camps stronger, armor raises your mistake tolerance, and the Mechblade (Light) makes clean parries pay off with more damage.

Charms add a small RNG layer after decoding, but the containers themselves stay fixed. Loot them every run, then let the result shape Koo’s support setup until stronger options open.

Walker base upgrades and meals

After the route, keep checking the tops of circular metal structures that look like mushrooms on the map. These can hold Walker modules such as a Facility Module, which expands what your moving base can support.

Koo also helps exploration between fights. When you enter a new area, he can mark items on the map, and later upgrades expand that tracking to hidden items; missed strongboxes and loot markers remain visible for cleanup.

Koo’s bond rises naturally through combat, but base interactions speed it along. Higher bond ranks unlock more slots and automatic combat options for healing, damage, debuffs, taunts, and other support skills.

Do not leave the Walker hungry. Gather fish, eggs, rice, plants, seeds, and recipes, then have Kagura prepare meals that give long-lasting buffs to HP, defense, attack, and skill power; better reputation with Kagura opens stronger recipes over time.

Key cleanup after the third subcity

The Red Key and Blue Key cleanup comes later in the early game, after you reach the third subcity near the route to the second main boss. Do the main power route first, progress the story, then loop back through these locked areas before committing to the next major fight.

On that same story stretch, watch for the Citrus Sword. It has Attack 27, and Clear Skies increases Emma’s damage by x1.02 and Koo’s damage by x1.02 for 5 seconds.

Early mistakes that slow the first region

Do not rush region bosses while the Fire Arrows manual, Acid Bolts manual, Chain Mail, and early Koo items are still sitting behind short side routes. Forcing progress with starter gear mostly spends healing and time.

Keeper Golems are not background NPCs; their chat options point to weapons and recipe locations, and one later hands over the Red Key. Bring Koo into fights, use camps near boss arenas before attempts, and treat support slots as part of the build.
