Play the Roaring Knight boss fight from DELTARUNE Chapter 3 for free, right in your browser, on PC or mobile. No download needed. Fight alongside Susie and Ralsei and dodge every one of the Knight's attacks with your SOUL.
The battle logic is ported from the original game, so the attacks, damage, TP and ACTs work like the real fight. Turn on Easy Mode in OPTIONS to take half damage while you practice.
Z or Enter: confirm X or Shift: cancel Arrow keys: move Esc or P: pause. On phones, use the on-screen pad and buttons, and the PAUSE button at the top.
Gamepad: plug in an Xbox, PlayStation or Switch controller and press a button. A/Cross: confirm B/Circle: cancel D-pad or left stick: move Start: pause. Click the page or press a key once to turn on the sound (browsers require it).
Remap the buttons in OPTIONS → CONTROLS (keyboard and gamepad). OPTIONS also has the volume and hats for your SOUL.
Choose EQUIPMENT on the title screen to pick each character's weapon and armors (any Chapter 3 gear they can use, including the ShadowMantle the Knight aims at) and the items you bring into the fight.
Choose PRACTICE on the title screen (or open practice mode directly) to dodge the Knight's attacks in order, Bad Time Simulator style. Lose your whole HP bar and the attack restarts; survive it and you move on to the next one. You can start from any attack and pick 90 HP, 45 HP or 1 HP (no hit). Every cleared attack scores points (more without getting hit, more for grazing, more on harder HP), retries cost points, and your best full run is saved.
For free practice, sandbox mode repeats any attack forever: press [ and ] to switch attacks and I for invincibility.
