COLLISION MECHANICS

Attack Pattern Archetypes & Avoidance Rules

DELTARUNE danmaku generally falls into four mathematical trajectories. Recognizing the pattern instantly dictates where you should park your soul.

🌀

Concentric Spirals (Spades & Scythes)

Seen on: Jevil, King

Bullets spawn in a pinwheel from a central origin and accelerate outward.

Optimal Line: Never run in the direction the spiral is spinning! Orbit against the spin near the outer rim, taking tiny rhythmic taps.

🌊

Vertical Oscillators (Carousel & Acid Droplets)

Seen on: Jevil Carousel, Queen Acid Drops

Columns of hazards move horizontally across the box while undulating up and down.

Optimal Line: Do not move horizontally! Position yourself in a vertical corridor and track only the highest and lowest bobbing crests.

💥

Explosive Clusters (Pipis & Heart Bombs)

Seen on: Spamton NEO

Primary projectiles drift slowly, then burst violently into 4–8 directional shards.

Optimal Line: Shoot or detonate them when they are far away from your soul so the expanding cone of shards dissipates before reaching you.

⚡

Telegraphed Reticles & Slashes

Seen on: Queen Lasers, Tasque Manager, The Knight

Lanes flash red or show tracking lines 0.5–1.0s before the deadly hitbox activates.

Optimal Line: Bait the tracking line into one quadrant, then immediately step 20 pixels sideways into a safe adjacent corridor right before ignition.

PRO ADVICE

Universal Dodging & Graze Tips

Understanding the "True Hitbox"

The visible Red Soul sprite in DELTARUNE is approximately 16x16 pixels, but the lethal hurtbox is only a tiny 4x4 pixel point at the exact center. You can clip bullet edges through your soul's outer rim without taking a single point of damage!

Graze TP Farming Loops

Grazing bullets with your soul's aura fills your Tension Point (TP) meter. Two good grazes award enough TP to cast Ralsei's Heal Prayer or Susie's Rude Buster a turn early. Always skim the edges of slow projectiles during early battle phases.

Never Hold Arrow Keys

The #1 cause of death in secret boss fights is overshooting. Tap arrow keys gently rather than holding them down. In dense storms, micro-tapping moves your soul by single pixels, keeping you inside narrow gaps.

Corner Traps Are Fatal

Dodging into a corner of the bullet box severely restricts your movement options to only 1 direction. Whenever possible, reset your soul toward the lower center lane (bottom 25% of the box) between bullet waves.

EQUIPMENT & REWARDS

ACT (Pacifist) vs FIGHT (Violence) Comparison

Every secret boss in DELTARUNE offers two mutually exclusive equipment rewards upon defeat.

Boss	🕊️ ACT Route (Mercy)	⚔ FIGHT Route (Violent)	Community Recommendation
Jevil	Jevilstail (Armor) +2 ATK, +2 DEF, +2 Magic. Equipable by anyone.	Devilsknife (Weapon) +5 ATK, +4 Magic, -10% TP cost for Rude Buster (Susie only).	ACT Route (Jevilstail): Outstanding universal defensive and magical armor that remains top-tier through later chapters.
Spamton NEO	Dealmaker (Armor) +5 DEF, +5 Magic, +30% Gold bonus in all battles.	Puppet Scarf (Weapon) +8 ATK, +6 Magic (Ralsei only, turns Ralsei into an attacker).	ACT Route (Dealmaker): +5 DEF and massive gold generation make Dealmaker arguably the best armor in Chapter 2.
