You enhance your powers with an elemental spike.
Manifester level 3rd
When you take this feat, you must make two choices: you must choose any one power you know that targets one creature and which is not a ray or touch power, and you must select a favored energy type (fire, cold, acid,
electricity, or sonic). When you maintain your psionic focus, the power you designate is psionically spiked with your chosen energy type and so deals +1d6 points of the appropriate type of damage in addition to its normal effect—if it takes effect.
You can take this feat multiple times. Each time you take it, it applies to a new power you know.
