The prologue of "The Blood of Dawnwalker" presents players with a seemingly insurmountable boss, Brencis, the Knyaz of Vale Sangora. While the game is structured for players to lose this initial encounter and progress the story, it is possible to achieve victory through mastering the game's combat mechanics.

Defeating Brencis in the prologue triggers a special cutscene. In this sequence, Brencis reveals his true form, becoming Brencis, Grotesque Ascendant, who also serves as the game's final boss. This early confrontation with the ultimate antagonist offers a glimpse into the game's narrative and potential endgame scenarios.

Despite this early victory, overcoming Brencis, Grotesque Ascendant, is presented as an extreme challenge. Even with the strongest available equipment on the first day of gameplay, damage dealt to this form is minimal, and a single hit from the boss results in player death, regardless of health upgrades. The boss also features multiple health phases that increase in difficulty, and the inability to quicksave means any attempts at this phase require replaying the initial fight against regular Brencis.

Players determined to attempt this feat are advised to focus on increasing damage output, as survivability against the Grotesque Ascendant is unlikely. Utilizing the speed of vampire claws and employing the Shadow Step ability to evade unblockable attacks and flurries is recommended. For those struggling, switching the game's difficulty to 'Story' mode may offer a more manageable path to witnessing the outcome of defeating Brencis's second phase, though the challenge remains significant.
