• What They Are: Objects imbued with Mana Circuits that produce repeatable effects when powered by Refined Mana Stones. - Key Differentiator: Unlike Ritualist ink or Mage spells, these effects are pre-programmed and user-agnostic—anyone with a stone can trigger them.

1. Circuit Embodiment: - Etched or inlaid circuits channel mana along predetermined paths. - Example: A fire-sword’s blade might have a branching "vein" pattern to distribute heat evenly. 2. Activation: - Inserting a Refined Mana Stone into the item’s "hub" (e.g., a pommel slot, lamp base) powers the circuits. - Effects persist until the stone is depleted or removed. 3. Control Interfaces: - Simple Items: Single-effect (e.g., a mana-lamp’s "on/off" rune). - Advanced Gear: Toggle-able modes (e.g., a shield alternating between "ward" and "rebound" settings).

• Decay: Circuits degrade under Tower mana turbulence (Alchemists often repair them mid-delve). - Bleed: Poor insulation causes "mana leaks"—unintended effects (e.g., a healing bracelet overheating the wearer). - Stone Dependence: No stone = fancy paperweight. High-tier items guzzle mana, making them expensive to run.

• "The Mana Guild’s seal on the hilt meant it wouldn’t explode. Probably." - "Enchanted items democratized magic—assuming you could afford the stones to feed them." - "A sword with circuits is just a sword. A sword with understanding is a ritualist."
