Build a stained-glass war-flower. Break its rules. See how far it grows.

PRISMBLOOM is an automatic-combat roguelite engine-builder about assembling a six-weapon crystalline Crown in the middle of a hostile garden.

Enemies advance along six curling paths. Your Crown chooses its targets and fires automatically. You decide what weapons it grows, which colors they carry, how their effects connect, and whether the resulting machine becomes elegant, efficient, or completely unreasonable.

Every defeated enemy creates Threat. Earn enough and you bank a Bloom—a free card choice that waits until you decide to open it.

Add another weapon. Rank up one you already have. Make one color trigger another. Rewrite a global rule. Mutate a weapon into a new behavior. Accept a dangerous bargain. Then return to the battle and watch the consequences spread across the entire garden.

Every Crown starts small.

The best ones become difficult to explain.

BUILD AN ENGINE, NOT JUST A STAT SHEET

PRISMBLOOM’s upgrades are designed to trigger, repeat, convert, and compound.

A Blue effect can trigger Green poison and roots. Every root can release Purple chain lightning. Critical hits can start their own electrical storms. Poison kills can feed your Dew economy. Marks can absorb burning damage before they burst. One color can activate the next until the entire Crown becomes a self-sustaining loop.

Build with:

• 12 distinct weapon forms

• Seven mechanical color identities

• 84 weapon-and-color combinations

• 115 curated engine cards

• Cross-color Laws

• Global Perks

• Weapon-specific Mutations

• High-risk Omens

• Branching weapon upgrades and final forms

• Grafts that join neighboring weapons

• Boss Relics that continue evolving across victories

The strongest builds do more than increase damage. They create systems that generate attacks, statuses, currency, shields, critical hits, and additional triggers faster than the enemy can contain them.

BUILD A SIX-WEAPON CROWN

Every weapon occupies one of six sockets around the Heart.

Fire precise needles, launch delayed seed pods, grow orbiting familiars, hold beams on priority targets, strike entire lanes with rings and fans, spread clouds of poison, throw returning Prismarangs, stitch enemies together, or drill into a boss until the whole engine overheats.

Weapon placement matters. Neighboring colors create seams with additional effects, while grafts combine two weapons into a driver-and-payload pair.

Specialize in one reliable tool or fill every socket with a different piece of machinery.

MAKE EVERY COLOR MATTER

Each pigment has its own combat identity:

• Yellow creates Dew and rewards a thriving economy

• Pink stores damage in marks before releasing it in delayed bursts

• Blue slows advancing enemies

• Red burns targets and spreads fire when they fall

• Green poisons enemies and periodically roots them in place

• Purple chains damage through nearby targets

• White releases volleys carrying multiple colors

Build a monochrome Crown around one dominant behavior, connect complementary colors, or assemble a full spectrum where every effect starts another.

Your garden might become:

• A poison engine that feeds on rooted enemies

• A recursive storm of marks and lightning

• A fortress of shields, control, and knockback

• A rapid-fire factory powered by kills

• A held-Dew economy that grows stronger the longer you resist spending

• A six-color reaction that never seems to finish

GROW AT YOUR OWN PACE

Each run begins with one Opening Bloom before entering the Continuous Garden.

Survive five finite waves and a multi-phase boss. Auto Next keeps the garden moving after each visible transition, or you can turn it off and start the next wave when you are ready.

Ordinary wave clears never force another card or shop visit. Banked Blooms wait for you. Run upgrades, services, and risks remain optional.

During the run, temporary Dew can be spent on:

• Six uncapped Run Upgrade lanes

• Card rerolls

• Heart repairs and shields

• Individual weapon damage, speed, and critical improvements

• New weapons and recoloring

• Socket swaps and weapon grafts

• Reward forecasting

• Other deterministic Dewworks services

Open the live build drawer while the battle continues, reinforce a weak Crown, or save your Dew for effects that scale with how much you hold.

When you want more pressure, Rush the current wave to pull additional enemies into the garden immediately and earn bonus Dew if you survive.

TAKE RISKS WITHOUT STOPPING THE RUN

Optional one-wave risk offers appear during the Garden Cycle.

Accept a dangerous modifier for an additional reward or dismiss it and keep moving. Empower elites, accelerate the assault, compromise your defenses, or bet that your engine can handle a sudden change in the rules.

These decisions never block the garden. The run continues because you chose to push it—not because an intermission demanded an answer.

DEFEAT THE BOSS. THEN DECIDE.

Clear the five Garden Cycle waves and face your selected boss.

Bosses introduce phases, reinforcements, telegraphed attacks, and mechanics designed to expose weaknesses that ordinary enemies could not. Defeating one secures the victory and grants a Boss Relic.

Then choose:

End the run, bank your permanent Gold, and visit the Workshop.

Or continue with the same build into Overgrow.

Overgrow is an endless post-victory challenge built from four escalating ordinary tiers followed by a recurring boss on every fifth tier. Each defeated boss offers another Relic and another chance to continue.

The original victory remains secured.

Everything after that is about discovering when the machine finally breaks.

GROW BETWEEN RUNS

Dew belongs to the current run. Gold survives.

Invest permanent Gold across six uncapped Workshop lanes covering weapon power, attack speed, Heart, critical chance, Dew production, and defense. Every five ranks reaches a new milestone that strengthens the lane and unlocks additional possibilities.

Account progression also expands:

• Starting weapons and colors

• Guided build packages

• Advanced run configuration

• Boss and Boss Relic choices

• A persistent Skill Tree

• Ten disclosed Challenge Levels

• New cards and services

• Bloomarium discoveries

• Build-defining permanent rules

The Bloomarium records every weapon-and-color combination you successfully bring to life, along with discovered cards, defeated bosses, and Boss Relics.

Permanent progression provides both new possibilities and lasting power. Later runs begin with more options—but still demand a coherent engine.

LEARN FROM EVERY CROWN

Detailed results explain what happened.

Review average and peak DPS, largest chain, waves cleared, Overgrow tier, Dew earned and spent, rerolls, services, permanent Gold, top damage sources, progression gains, records, and the event that finally broke the Heart.

Then decide what comes next:

• Retry the same build with a new deterministic seed

• Replay the exact same setup and seed

• Return to setup and grow something completely different

Death is not the end of a build.

It is the moment you understand what it was missing.
