What is the FULL Roaring Knight remake?
The FULL Roaring Knight remake is a highly polished, community-created boss fight. It imagines the ultimate final battle of Deltarune against the entity responsible for opening the Dark Fountains, complete with original attack concepts, party management, and a unique soundtrack.
Battle Mechanics
- The Shadow Mantle: A core mechanic in this fight. You can choose whether Kris, Susie, or Ralsei holds the Shadow Mantle, which grants different passive buffs like increased HP, better healing, or turn advantages.
- Party Actions: Just like official Deltarune battles, you manage TP (Tension Points) to cast spells. Perfecting your dodges (grazing) rewards extra TP and damage boosts.
- Focus Movement: Holding down the Z (Confirm) key during enemy attacks will slow down your SOUL, allowing for much more precise dodging during dense bullet patterns.
Tips for Beating the Roaring Knight
- Slow Your SOUL: Remember to hold Z when attacks get too dense. The slower movement speed is essential for weaving through the Knight's custom sword attacks.
- Graze for TP: Try to get close to bullets without touching them. Grazing not only builds TP for Ralsei's healing spells but also provides a damage boost.
- Choose the Right Mantle Holder: If you are dying too quickly, give the Shadow Mantle to Kris for maximum survivability. If you need more sustain, give it to Ralsei to boost his healing output.
- Defend When Overwhelmed: If you are out of TP and low on health, have the entire party Defend. This reduces incoming damage and passively builds the TP needed for a heal on the next turn.
- Instant Respawn: If you die, hold the X or Shift (Cancel) key during the game over screen to instantly restart the fight and skip the intro dialogue.
Frequently Asked Questions
Is the Roaring Knight an official Deltarune boss?
No, this is a fan-made concept battle created by Gangstermango. While the Knight is a real character in Deltarune lore, Toby Fox has not yet revealed their official boss fight.
Why is the game lagging during sword attacks?
This fangame features incredibly complex custom attacks. Ensure that your browser has hardware acceleration enabled, as it relies on your GPU to render the bullet hell smoothly.
Who should hold the Shadow Mantle?
It depends on your playstyle. Kris provides raw defensive stats and HP, Susie maximizes your damage output, and Ralsei optimizes your TP generation and healing power.
How do I use the slow movement feature?
During the enemy's turn, hold down the Z (or Enter) key. This halves your SOUL's movement speed, making it much easier to squeeze through tight bullet gaps.
What happens if Ralsei is downed?
Like in Deltarune, if Ralsei is downed, you lose your primary source of healing. Prioritize using items on him or defending until he recovers so you don't get wiped out.
