Countermeasures

This supplement adds tools for hindering or neutralizing psionic powers, including three feats, more than fifteen items, an organization, a location, and a prestige class. The rules are intended for players and game masters facing psionic creatures, and can also apply to magic in campaigns that use psionic-magic transparency.
