+    Weapon of Energy
+
+    Psychokinesis [see text]
+    Level: Psychic warrior 4
+    Range: Touch
+    Target: Weapon touched
+    Duration: 1 round/level
+    Power Points: 7
+    Metapsionics: Extend
+
+    You can use this power to energize a weapon. That weapon deals an extra 1d8
+    points of cold, electricity, or fire damage (as chosen by you at the time of
+    manifestation) on a successful hit.
+
+    If this power is manifested on a already benefiting from the effect of the
+    power, the newer manifestation supersedes the older manifestation, even if
+    both manifestations are of different energy types.
+
+    This power<65>s subtype is the same as the type of energy infused in the
+    touched weapon.
