What the Preview Establishes
The Fallen is a sewer boss described in Corey Brotherson's PlayStation hands-on. The author reports Holy Cross bludgeoning and a screen-reaching whip attack, and describes leaping over the Cross or whip. These observations support an encounter overview; they do not establish an exhaustive move list.
Use the bosses overview to distinguish this reported encounter from bosses named on the official product page. The preview build and KONAMI's public demo are separate sources, so we do not assume this fight appears in the public demo.
Preparation Suggestions
Practice jumping and the PS5 preview's Circle dodge and double-tap backflip before attempting unfamiliar fights. Treat this as general preparation: the source does not give precise jump timing, recovery windows, phase thresholds or a guaranteed counter sequence.
During your own encounter, watch the attack before committing to a response. A successful jump in the report does not prove every variation can be avoided the same way. The combat guide explains the controls without assigning frame counts.
Holy Cross Reward
The hands-on report states that the Holy Cross becomes Rose's after The Fallen is tamed. It places boss rewards in the tarot-based Arcana system. The linked source does not specify a rotating projectile pattern, damage value or exact mana cost for this reward.
The reported reward is Holy Cross. The report also describes the Arcana Whip grapple as an ability, but does not give its acquisition route. Neither detail supports inventing a whip unlock from this boss.
Details Still to Verify
A complete fight guide needs evidence for the route, attack sequence, phase changes and reward behavior in the released game. Those details remain unverified in the sources used here. Check the official product page for current release information.
