Threat Range

The threat range for a weapon indicates the likelihood of scoring a critical hit with that weapon. A weapon's threat range can be increased through the keen item property and the Improved Critical, Ki Critical and Overwhelming Critical feats.

The table below begins with the unmodified threat range and then stacks individual or a combination of feats to achieve the maximum threat range possible for a typical 18-20, 19-20 and 20 threat range weapon.

Feats	Kukri, Rapier, Scimitar	Crossbows*, Dagger, Heavy Flail, Swords, Trident	All Others
Unmodified base	18-20	19-20	20
With either Keen or Improved Critical	15-20	17-20	19-20
With both Keen and Improved Critical	12-20	15-20	18-20
With Ki Critical or Overwhelming Critical	16-20	17-20	18-20
With Ki Critical or Overwhelming Critical and either Keen or Improved Critical	13-20	15-20	17-20
With Ki Critical or Overwhelming Critical and Keen and Improved Critical	10-20	13-20	16-20
With all four	8-20	11-20	14-20

* Crossbows do not benefit from ki critical.
