The "Power System" is the core engine of gameplay integration. The AI must understand exactly how players spend resources to trigger effects. Vague magic systems will result in generic, unplayable mechanics.
Your document MUST explicit define these three terms:
The resource spent.
What powers are called.
Measurement of strength.
The System needs to know limits. An "anything goes" magic system is impossible to gamify. You must define costs and consequences.
