⚡ Magic System Interactions

Opposite Actions (Violent Clash)

Divine ↔ Infernal

Brutal opposition. Higher spell level wins. Equal levels = both fail + damage.

Arcane ↔ Fae

Violent opposition. Compare mana/slot levels. Equal = mutual destruction.

Circle of Interference (Gentle Disruption - Clockwise)

Divine → Fae → Infernal → Arcane → Divine

Force concentration check (DC 10 + spell level). Disrupts casting, not ongoing effects.

Circle of Enhancement (Reinforcement - Counter-clockwise)

Divine → Arcane → Infernal → Fae → Divine

Combine for enhanced effects. Roll d20 for stability (1-3=fail, 18-20=spectacular). Note: Infernal → Fae is SAFE (no corruption).
