In Deltarune, Rouxls Kaard makes a comeback as a familiar yet comedic figure. First appearing in Chapter 1 as the self-styled “Duke of Puzzles,” he took on roles like a bumbling blocker and merchant. His Chapter 2 return keeps him in the realm of humor, though his role evolves slightly.
This time, Rouxls presents a more tangible challenge as a boss encounter. Below is a detailed walkthrough for overcoming his antics in the game’s second chapter.
Rouxls Kaard’s Game Mechanics in Deltarune Chapter 2

Players can tackle Rouxls through combat or strategy. Opting for violence speeds up the battle—he only has 600 HP, manageable even without Susie’s help. Kris and Ralsei must handle attacks solo.
Pacifists face a quirky territorial mini-game. Each turn lets players claim adjacent tiles starting from one owned. Multiple claims cost TP, while Ralsei’s distracting ACT reduces Rouxls’ tile placements. Victory isn’t mandatory: Even if Rouxls dominates tiles, the battle progresses identically. His futile “ultimate attack” always backfires, immobilizing him temporarily.
Strategies to Overcome Rouxls Kaard




To expedite the puzzle, expand your territory diagonally to block Rouxls’ starting tiles. This forces an early conclusion, skipping prolonged gameplay. Regardless of tile counts, the battle concludes with Rouxls’ comedic defeat, letting players advance.
Mastering these tactics ensures swift progression past this eccentric antagonist in Deltarune’s latest installment.
