HP (Start): 13/225
Energy (Start): 85/100
Spirit (Start): 142/172
Use spirits: Guts then (if it stacks with the maneuver) Valour
Enter Stance: Way of the Sword - Main Weapon
Standard Action: Colossal Strike.
HP (End): 225/225
Energy (End): 20/100
Spirit (End): 72/142 OR 112/142.Attack Roll: 49, hitting touch AC.
Damage is rending, and I'm not sure how these stack.
If Valour can't stack with Colossal Strike:
If Valour stacks with Colossal Strike like crits (so x3):
If Valour stacks with Colossal Strike and doubles completely (so x4):
And in each case, if it's just "double the first rolled damage"), the damage would be: 172/258/344
