Following the defeat of the Crimson Malefact and reunion with Koo in the Inukami River Zone, players of Beast of Reincarnation will progress to Chapter 10, titled Malefact, which takes place in Starfall Tower. This guide details the path through the tower and the strategy for defeating its Nushi.
Upon arriving at Starfall Tower in the Wasteland Region, the primary objective is to reach the deepest level and challenge the Nushi. Koo's Bloom Arts and Skills become available again during this chapter.
Navigating Starfall Tower
The journey begins by heading to the deepest floor of Starfall Tower. After departing the Cleanse Walker, activate the elevator. As you descend, listen to a transmission from Brad, which will conclude upon arriving at the Starfall Tower: Entrance Campsite. Proceed through the door to the right. Initially, progress is blocked by a locked bulkhead door, necessitating upward movement using Emma's hair. Interacting with a Control Panel will open this bulkhead door, allowing passage.
A second Control Panel will open another bulkhead door located near the Entrance Campsite. After passing through this, you will reach the Starfall Tower: Interior Campsite. Here, a large lever is situated next to a third bulkhead door, but interaction is blocked until Brad's transmission concludes. Once the transmission ends, rest at the Campsite and then interact with the lever to open the next bulkhead door. Beyond this door, a group of invisible Golems must be defeated by attacking them to force them to uncloak.
Continue past the Golems to reach another elevator, which descends further into the tower. At the bottom, after another transmission from Brad, unlock the Starfall Tower: Control Room Campsite. Nearby, a second lever with a glowing red light will be present, but it lacks power. To restore power, head right from this lever and enter the building ahead, ignoring the stairs for the moment. Follow the linear path to the rightmost section of the building to find and activate a Control Panel. Return to the building's entrance and take the leftmost path. Ascend the first staircase on your right to find and interact with a fourth Control Panel. With all Control Panels activated and Brad's transmission finished, return to the unpowered lever. Ascending the stairs to the right of the lever will lead to another Control Panel. Interacting with this panel will finally power the lever. Use the lever, being mindful of a Golem enemy that spawns as you leave.
The huge bulkhead door to the left of the lever will now be open, allowing further progress towards the objective and signaling entry into the Forest Grotto. Continue along the linear path, keeping to the right, until you reach the In Front Of The Lab Campsite. Ahead is another bulkhead door that requires locating and interacting with its corresponding Control Panel. To reach this panel, use Emma's hair to ascend the steel pipes directly to the left of the Campsite. Look opposite the water below to find the Control Panel. After interacting with it, the bulkhead door will open.
Pass through the bulkhead door and proceed towards your objective. A cutscene will play, during which you will acquire the Kanzashi, a key item.
Defeating the Nushi: Ursa
With the Kanzashi obtained, advance to the end of Starfall Tower to confront the Nushi. Continue north through the lab towards your objective, encountering and clearing out bear malefacts. In the back left corner of this room, find and interact with a Dragon Vein Shrine.
Just past the Shrine, you will find the Nushi's Lair Entrance Campsite and a Merchant Golem. This is an opportune moment to rest and prepare for the upcoming boss battle. Enter the arena ahead to face the Nushi, a Level 46 Ursa, which is a boar/bear-like creature and a larger variant of the bear malefacts encountered earlier.
Ursa is vulnerable to the Acid element. The Hazebringer sword, Nobudou Blade, and Bloom Arts are recommended. Additionally, bring Bottles of Acid or Koo's Corrosive Fang Skill Amber. To restore FP and stagger the boss, parrying its paw swipe combo is effective. Be prepared for increased attack tempo and damage when the Ursa imbues itself with blight. The boss has two health bars, so manage your Stimpacks and utilize Koo's Bloom Arts for healing.
Upon defeating Ursa, players will be returned to the Cleanse Walker and will receive the Asagao: Boa 2 Bloom Art and the Finisher: Asagao 1 Blade Art. This concludes Chapter 10, with Chapter 11 taking place in the Mount Hiei Zone. For further assistance with Beast of Reincarnation, consult guides on Skills, Strongbox codes, and how to respec.
