World Economy & Crafting

World Economy & Crafting

Core Currency: Monster Cores

Monster Cores are crystallized remnants of defeated enemies—raw data, soul-echo, and system residue fused together.

They function as:

  • A universal crafting & purchase currency

  • A gacha entry token

  • A narrative artifact (NPCs know where these come from)

Monster Cores are earned by:

  • Defeating monsters (rarity scales with threat)

  • Boss clears

  • Dungeon objectives

  • World events / seasonal content

  • Rare drops from elite or anomaly creatures

System 1: Relic Invocation (Gacha System)

This is the flashy, MMO-brain-activating route—but with guardrails.

In-World Framing

Players are not “rolling lootboxes.”

They are:

  • Invoking Relics

  • Synchronizing with dormant echoes

  • Drawing from the World Archive

  • Reconstructing lost arms from monster memory

Think glowing circles, chanting NPCs, ancient terminals, or living shrines.

How It Works

  • Spend Monster Cores to perform an Invocation

  • Results in equipment, relics, or augment items

  • Loot pools are tiered and transparent

Example tiers:

  • Common (Utility gear, consumables, low-tier augments)

  • Uncommon (Solid weapons, armor, set pieces)

  • Rare (Named gear, unique passives)

  • Epic (Build-defining items)

  • Legendary/Mythic (World-significant relics)

Pity & Protection (Very Important)

To keep this table-safe and non-toxic:

  • Soft Pity: Guaranteed Rare+ after X invocations

  • Hard Pity: Guaranteed Epic after Y invocations

  • Duplicate Conversion: Extra copies break down into:

    • Monster Core refunds

    • Upgrade materials

    • Targeted invocation tokens

No one should feel punished for bad luck.

System 2: Direct Purchase (In-Game Economy)

This is the reliable path—the one planners and roleplayers will love.

Vendors & Sources

Players can spend Monster Cores at:

  • NPC blacksmiths

  • Arcane forges

  • Beastkin traders

  • Guild quartermasters

  • System-adjacent vendors (questionably sentient ones 👀)

What Can Be Bought

  • Standardized weapons & armor

  • Class-appropriate gear

  • Crafting materials

  • Upgrade components

  • Cosmetic variants

  • Limited rotation items

Think:

“This won’t break my build—but it will work.”

Rotation & Scarcity

To keep things fresh:

  • Vendors rotate stock by:

    • Region

    • Season

    • World state

    • Player progression tier

  • Some items disappear if:

    • A town falls

    • A faction turns hostile

    • A world event concludes

The economy remembers.

Optional System 3: Crafting & Ascension

Monster Cores also fuel intentional progression.

Players can:

  • Upgrade gacha gear into deterministic versions

  • Reforge items to reroll stats

  • Ascend gear to higher tiers

  • Fuse monster traits into equipment

This creates a loop:

Gacha → Salvage → Craft → Personal Relic

Your sword stops being “Epic Drop #47”
and starts being your sword.

Why This Works for Eidolon Online

  • No permadeath pressure → players can experiment

  • Soft-death philosophy → gear loss is rare or narrative-based

  • Identity-forward design → equipment reflects playstyle, not RNG suffering

  • NPC respect → powerful gear has presence in the world

NPCs might say things like:

“That blade… you didn’t buy it. You called it back, didn’t you?”

TL;DR Loop

  • Kill monsters → get Monster Cores

  • Spend cores on:

    • 🎲 Relic Invocation (gacha, protected)

    • 🛒 Direct purchase (reliable)

    • 🔨 Crafting & upgrades

  • Gear gains history, not just stats
