Lingering Spirit (SU) - Reanimated Medium

[Balanced]

"At 5th level, a reanimated medium's spirit lingers for up to 1 round after death before departing if the medium spends 1 point of influence. If the reanimated medium died of hit point damage, healing works on his body during the intervening round and can bring him back to life. Once the spirit departs, the breath of life spell continues to work for 1 additional round, even though the reanimated medium has been dead for more than 1 round. This ability replaces location channel."

Does that mean I can keep spending influence to add an additional round of lingering my spirit? Or does it work only once?

[Saethori]

The wording implies it's a choice to spend one influence or not at that time.

>Medium dies. Ability allows her to spend one influence.
>If she spends the influence, then for the first round after her death, curative magic works on her, and for the second round after her death, Breath of Life works on her.
>If she does not spend the influence, then curative magic other than Breath of Life does not work, and Breath of Life has its usual one round window.
