🌠616th Expeditionary Corps

⚔️ Artifact Guide — 616th Expeditionary Corps

How are the powers of each NFT defined ?

---

🕯️ 1. Introduction

The artifacts of the 616th Expeditionary Corps are high-order tactical relics forged in off-world campaigns. They merge advanced engineering, temporal manipulation, and arcane warfare protocols.

When equipped by a Lion, each artifact becomes a unique combat module:

• A direct strike based on its offensive frame.

• One or more secondary effects defined by its body type.

• Mana cost, damage scaling, and effect duration generated dynamically from its traits.

Every artifact is fully determined by four core traits:

• Body → defines the power (ability type and effect package).

• Backpack → defines the direct damage multiplier (% of ATK).

• Background → defines the mana cost.

• Color → defines the duration (turns_left) of applied effects.

No randomness in design: the NFT metadata is the blueprint.

⚙️ 2. Core Trait System

2.1 Body — Power & Effect Identity

The Body determines:

• The primary power (ability identity).

• The mechanical effect(s) applied.

• The English power name and description.

This is the logic hook you already use from metadata → effects_json.

3. Generated Power Summary

For any 616th Expeditionary Corps artifact:

1. Read Body → choose the Power and its effect type(s).

2. Read Backpack → set damage_percent_atk for the direct strike.

3. Read Background → set mana_cost.

4. Read Color → set base turns_left for the effects.

This keeps the entire system deterministic, fully on-chain/metadata-driven, and perfectly aligned with your arena engine.
