Master the brutal Roaring Knight secret boss with optimized strategies, equipment setups, and advanced combat techniques
Introduction: Understanding the Challenge


The Roaring Knight in Deltarune Chapter 3 represents one of the most demanding optional encounters in the entire series. This brutal secret boss emerges following the Teena confrontation during the chapter’s climax, presenting players with a genuine skill check rather than a gimmick-based puzzle battle. Proper preparation, precise equipment selection, and flawless execution become absolute necessities for survival. Attempting this encounter without the Shadow Mantle typically results in party annihilation within just a few combat turns due to the overwhelming damage output.
Understanding the fight’s design philosophy is crucial – this encounter tests your mastery of game mechanics rather than offering a traditional RPG experience. Each attack pattern demands specific countermeasures, and there’s minimal room for improvisation once the battle commences.
Essential Equipment and Party Setup
Optimal gear configuration forms the foundation for any successful Roaring Knight attempt. The recommended loadout maximizes survival potential while maintaining adequate damage output:
This equipment distribution establishes clear combat roles: Susie operates as the primary damage dealer and frontline tank utilizing the Shadow Mantle’s defensive properties and Toxic Axe’s consistent damage. Kris provides secondary damage output and status effect application with the Saber10, while Ralsei focuses exclusively on support through healing and buff management. The Twin Ribbon accessories on both Kris and Ralsei significantly enhance their survivability against area-of-effect attacks.
For players seeking alternative setups, consider swapping Ralsei’s Flex Scarf for a second Twin Ribbon if healing consistency proves challenging. The Jevilstail on Susie provides crucial evasion bonuses that can create additional survival windows during the fight’s most intense phases.
