Deltarune Tips & Tricks: Pro Strategies & Hidden Mechanics

Deltarune is Toby Fox's followup to Undertale, released in episodic chapters starting in 2018. It blends a fixed party RPG with bullet hell dodging in battle, and your choice to fight or spare shapes the tone of each encounter.

These tips go beyond the basics. They're the strategies experienced players use to play more efficiently, the hidden mechanics most people miss, and the optimizations that compound over a full playthrough. If you're just starting, check our beginner's guide first.

Advanced Strategies

Build Optimization

The difference between an average build and an optimized one is massive. See our builds guide for full breakdowns.

For Kris the silent vessel (A-Tier):

• Focus on Bullet dodging battles synergies for maximum output.
• Core gear: Kris's various swords
• Stat priority: Offensive stats first

For Susie the reckless bruiser (A-Tier):

• Versatile approach that handles any situation.
• Core gear: Susie's axes
• Stat priority: Balanced stats

Mechanic Interactions

Understanding how Deltarune's systems interact is where the real optimization lives. Our combat guide covers this in detail.

Bullet dodging battles + ACT and mercy system: Defending means steering a heart through bullet patterns, so dodging skill protects the whole party each turn. Combined with ACT and mercy system, you can act on enemies to calm them and then spare instead of killing, opening a pacifist route.

Tension Point magic + Party of three combat: Grazing bullets and defending build TP, the resource that powers healing and attack spells. When paired with Party of three combat, unlike undertale's solo battles, you command a three character party each with distinct spells and roles.

Branching route choices scaling: Decisions and an optional hidden route change events, dialogue and the darker Weird Route outcomes.

Equipment Efficiency

Location Efficiency

Hometown (Story hub): The cozy overworld where Kris lives, connecting the chapters and townsfolk.

Field of Hopes and Dreams (Chapter 1): The opening Dark World area of Chapter 1 where Susie and Ralsei join.

Cyber World (Chapter 2): The neon Chapter 2 Dark World built around Queen and Noelle's arc.

Card Kingdom (Chapter 1): The card themed kingdom ruled by King, the heart of Chapter 1's climax.

The Dark Fountains (All chapters): The mysterious fountains whose spread drives the overarching plot.

Mistakes Even Veterans Make

1. Attacking every enemy out of habit and missing the recruitable pacifist outcomes.
2. Spending TP carelessly so you lack the resource for healing in a long boss fight.
3. Ignoring defense turns and taking avoidable damage instead of building tension.
4. Rushing past Dark World rooms and missing chests, items and secrets.
5. Entering bosses with an empty item inventory and no healing buffer.

Pro Quick Tips

• Spare enemies after ACTing them down if you want the intended pacifist route and its lighter tone.
• Build TP by grazing bullets close and defending, then spend it on healing and key spells.
• Use Ralsei's Pacify and heal spells to clear fights without killing and to keep the party alive.
• Start with Susie the reckless bruiser, switch to Kris the silent vessel when ready
• Invest in Kris's various swords above everything else
• Clear areas in order: Hometown → Field of Hopes and Dreams → Cyber World → Card Kingdom → The Dark Fountains. See our maps guide
• Bullet dodging battles + ACT and mercy system together are stronger than either alone
