Breakpoints use Reimagined’s weapon speeds, skill values, and animation timings. The game runs at 25 simulation frames per second. Cast-rate skills use FCR instead of IAS.

Wereforms assume you have the skill or item needed to transform. Normal attacks model the selected weapon. Special attacks without verified timing show an unavailable result.
