Effective at torporing, but rapid shots from a Rusted Bow will torpor quicker.
Morbidity further increases the torporing power of this skill.
The torporing power is increased further if used with an upgraded rusted bow - thus with Plegic Arrow, Morbidity and a 3* Rusted Bow, a Saurian is torpored in a single hit; whereas under the same conditions with Pleached Limbs it takes two Plegic Arrows to torpor.
Physical damage from Blunting to Plegic Arrow does not increase. Actual damage is a little better than that from a Quick-Loosed arrow.
