Spell Design Guidelines

Best practices and guidelines for creating balanced, fun, and engaging spells in OpenRoads.

🎯 Design Philosophy

Core Principles

1. Meaningful Choices - Each spell should serve a distinct purpose

2. Balanced Power - Power should scale appropriately with cost and requirements

3. Clear Feedback - Players should understand what spells do and why they succeed/fail

4. Thematic Consistency - Spells should fit the game world and element themes

5. Progressive Complexity - Simple spells for beginners, complex spells for advanced players

Player Experience Goals

• Accessibility - New players can understand and use basic spells

• Depth - Advanced players have complex options to explore

• Satisfaction - Casting spells feels impactful and rewarding

• Strategy - Spells create interesting tactical decisions

• Progression - Players feel growth as they unlock new spells

Conditional Spells

Different effects based on circumstances:

    stat_mod:
      hp: 50  # Base protection

Scaling Spells

Effects that grow with character power:

🚫 Common Pitfalls

Overpowered Spells

• Problem: Trivializes other options

• Solution: Increase costs, add restrictions, reduce power

• Example: Instant-kill spells, unlimited teleportation

Underpowered Spells

• Problem: Never worth using

• Solution: Reduce costs, increase power, add utility

• Example: High-cost spells with minimal effects

Unclear Purpose

• Problem: Players don't understand when to use the spell

• Solution: Clear descriptions, obvious benefits

• Example: Vague stat modifications

Poor Resource Management

• Problem: Spells that break the economy

• Solution: Appropriate costs and cooldowns

• Example: Infinite resource generation

Thematic Inconsistency

• Problem: Spells that don't fit the world

• Solution: Align with element themes and game lore

• Example: Technology spells in a fantasy setting
