As a Psychic, Svala receives a Phrenic Amplification. This is a proposal for a different ability on the list.

Retain Power (Su): By spending 1 point from her phrenic pool, the psychic can retain some of her power as charge. Doing so causes her a number of points of non-lethal damage equal to linked spell's level. When charged the psychic can release the charge as a standard action, dealing 1d6 damage per linked spell's level to every creature and object within 5 feet, except the psychic herself, with a Reflex save for half damage. The DC of the saving throw is calculated using the linked spell's level If she does not discharge, the energy dissipates over time, fully dissipating after an hour.
