Type: Metapsionic
Source: Dragon #287
You can modify a power that uses one type of energy to use another type of energy.
Benefit: Choose one type of energy: acid, cold, electricity, fire, or sonic. You can modify a power with an energy designator to use the chosen type of energy instead. A substituted power works normally in all respects except the type of damage dealt.
A substituted power costs a number of power points equal to its standard cost (there is no extra cost), modified by any other metapsionic feats.
Special: You can gain this feat multiple times, each time it applies to a different type of energy.
