How fast can you expend your Psionic Focus if you have Deep Focus feat?

Question

Deep Focus [Psionic] Prerequisite: Psionic Body, Autohypnosis 4 ranks.

Benefit: You can psionically focus your subconscious in the same manner in which you gain psionic focus normally. At any time when you need to expend your psionic focus, you can expend your subconscious’s psionic focus instead. At any time when you need to maintain psionic focus for an effect, you can use your subconscious’s psionic focus instead. Psionically focusing your subconscious works just like focusing your conscious mind.

Special: You cannot benefit from both Psicrystal Containment and Deep Focus at the same time. If you have both feats, you may only have your psicrystal or your subconscious maintaining psionic focus at any given time.

I assume focusing both would take full action. Now with feats that require expulsion of Pionic Focus and multiple attacks normally or with Rapid Shot or Two Weapon Fighting feats; can you expend both foci on multiple attacks or is restricted to once per turn/round?

Answer 1

There is no inherent action cost or rate limit on expending psionic focus; you may do so as often as you have a reason to do so so long as you have focus to expend. You can even expend two foci while manifesting a single power, to apply two metapsionic feats to it. Likewise, you could apply the “on expend” feature of two psionic feats to a single attack. Expending focus on subsequent attacks is also valid.

By the way, focusing either requires a full-round actions; focusing both requires two full-round actions. You could do it in one turn using Psionic Meditation, which makes each psionic focus take a move action. Also, for the record, Psicrystal Containment is much better than Deep Body (solely because Psicrystal Affinity is a good feat, while Psionic Body is garbage).
