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

Retain Power (Su): When casting a spell, the psychic can spend 1 point from her Phrenic Pool to retain some of her power, cycling it through her inscriptions instead of letting it go. Doing so causes her one point of non-lethal damage. Non-lethal damage from this ability can't be reduced or redirected. The Psychic cannot use this ability if she cannot take non-lethal damage and cannot use it if it would reduce her to 0 hp or less.

If she does, she gains one point of charge, which lights up her inscriptions and may occasionally cause crackles of energy to run over her skin, increasing in power and frequency if charge is built up over multiple uses.

As a standard action, the Psychic can release one point of charge, dealing 1d6 damage to every person and object within 5 feet, except the Psychic herself.

If she does not discharge, the energy dissipates over time, reducing the charge by one point per hour.

While charged, the Psychic cannot heal the non-lethal damage taken from this power or points used in her Phrenic Pool - she needs to discharge the energy first before being able to rest.
