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.
