Indomitable Will
In-game tooltip, talent: stack the Indomitable Will effect when attacked, with a brief interval between stacks. The keyword tooltip behind it: Indomitable Will increases Physical Resistance for a period of time, stacking up to 10 times. The interval is the part the spoken guide omits — stacks cannot be farmed off a single flurry.

When to use it
The defensive backbone of the parry build: blocking is already the play pattern, so the stacks accumulate as a by-product. Two further claims from creator coverage — that stacks build faster while blocking, and that a perfect block grants three at once — are not in either tooltip and are left as unverified rather than recorded as behaviour. The same guide estimated ten stacks at roughly 20% mitigation and said outright it was unsure, so no percentage is published.
