Spell Magnitude in This Mod: How Willpower and Resistances Work

You've might noticed most of this mods features actually nerf magic, so why is it called 'Mighty'? It's because of the Saving Throw module!

• Resistance or Tolerance to an element reduces incoming spell magnitude by 50%.
• Weakness or Phobia increases the magnitude by 50%.
• Critical Weakness increases it by 100% — meaning double damage.
• Immunity gives 100% reduction - making you immune to that effect.
• These effects stack together. For example:
  
  • If you have a Resistance and a Weakness to the same element, they cancel out.
  • If an enemy has Critical Weakness and Resistance, they will take 50% more damage (100% - 50%).
    

• 50 Willpower is the neutral baseline for both caster and target.
• If your Willpower is higher than 50, your spells get stronger.
• If your target’s Willpower is higher than 50, they resist the spell more effectively.
• The difference between caster and target Willpower acts as a percentage multiplier to the spell’s final magnitude.
  

• A caster with 100 Willpower casting on a target with 50 gets a +50% bonus to spell strength.
• If the caster has 50 and the target has 100, the spell is reduced by 50%.
• These bonuses and penalties are linear and balanced — so a 20-point difference gives a 20% modifier.
  

• You cast a Fireball with base 30 damage.
• The enemy has a Critical Weakness to Fire (+100%) and Resistance to Fire (-50%) → net +50%.
• You have 80 Willpower, they have 40 → a +40% bonus from Willpower.
