I felt challenged, so you get math!
Scalar Strike [Fighter]
Your attacks have exceptional damage capabilities.
Prerequisites: Int 13, Weapon Specialization
Benefit: Whenever you make an attack with the weapon for which you have Weapon Specialization, roll 1d6. If you roll an odd number, multiply the damage bonus from Weapon Specialization by half the value you rolled, rounded up. If you roll an even number, take the damage bonus from Weapon Specialization to the power of one-half the value you rolled.
Special: If you have Greater Weapon Specialization, add 2 to the value rolled for this feat.
Terrible Strength [Fighter][Epic]
Your attacks have a potential to deal egregious amounts of damage.
Prerequisites: Scalar Strike, Strength 31, BAB +20
Benefits: Whenever you use Scalar Strike, increase the order of the hyperoperation by one step.
Normal: Weapon Specialization doesn't have a chance to give you +65536 damage It just doesn't.
Terrible Strength is extremely unbalanced. But hilarious.
