Sure, let’s treat a spell like a small, tidy function. Think of it as 1. **Declare the function** `castSpell(target, power, spellType)` 2. **Validate inputs** * If the target is null or out of range, return error. * If the caster lacks enough mana, return error. 3. **Prepare the incantation** * Set a local variable `effectStrength = power * spellType.multiplier`. * Store the current mana in `oldMana`. 4. **Execute the core effect** * Apply `effectStrength` to the target’s health or status. * Reduce the caster’s mana by the cost of the spell. 5. **Post‑spell housekeeping** * Log the cast (optional). * If the target died, trigger death logic. * Return a result object: `{ success: true, damage: effectStrength, manaSpent: oldMana - caster.mana }`. Each line of the incantation maps directly to a line of code: “I bind fire!” becomes `applyDamage(target, effectStrength)`, “Shield the ally!” becomes `applyBuff(target, spellType.buff)`, etc. This keeps the spell readable, testable, and reusable—just like a clean function.

Exactly. Think of a spell like a quick script: you open the function, check the arguments, run the main body, and finally close it up cleanly. That way you can swap in different incantations without messing up the whole system. It’s the same logic that keeps your code modular and bug‑free.
