At first I liked the idea of Cantrips that could have better effect via the expenditure of a focus point. However, it seems clear that the intent is to not make them as powerful as your 'average' Slotted or Focus spell, both by the effects they give, and by the fact that they started the Psychic out with 2 Focus points dedicated to Amping their cantrips.
I thought that was kind of new and exiting. However I started to wonder about how that might cause problems with scaling issues for expected Focus point costs, and might cause additional problematic interactions with multiclass archetypes based on different scaled expectations of focus points. This concern seems visible in the wording that seems to insure that if you used a focus point for something other than Amp purposes, you can't recover both your focus points. Someone mentioned the way the wording for it seemed kind of rough, and was suggesting some simplifications, but I kept wondering if it was a good precedent to set, jumping to 2 focus points right away at 1st level.
I began wondering if you could instead have a focus point be able to be spent to AMP a cantrip, and would leave you with an Amped condition (similar to Panache). While Amped you could expend your Amped condition to make another cantrip you cast become Amped.
You might even be able to apply a bonus +1 status bonus to psychic spell attack rolls while Amped to represent an heightened attunement and awareness. Refous activity naturally removes the Amped condition. I imagine unleashing Psyche's would also unset the Amped condition.
That sort of leaves you with Amping sort of effectively costing a half a focus point to cast. And would also be available for free once a round if you accept a penalty of some sort from an Unleash that would normally be available later in any fight.
The potential of Amped condition being something that could boost spell attack rolls. Would be similar to a stance available early in combat, but at the cost of a focus point, and action(s) to cast a cantrip. Maybe the bonus to attack rolls wouldn't fly with the Amp condition, but I was trying to think of something small, but meaningful that might be worth tying to the state. I'd probably have the bonus apply to both the cantrip that powered/started the Amped condition, as well as the one that expended the Amped condition, if there was any question about that. But again, I'm not certain how that sort of bonus would be seen as affecting the balance.
It seems with fewer spells, higher reliance on cantrips (but slightly strengthened) that a slight boost on hit might be viable for them, in one mode of play.
I'd also liked the idea of potentially having slotted spells potentially count as one slot level higher (up to normal max spell level for the caster) in terms of incapacitation checks. That would allow the Psychic to have fewer spells, but more of them being potentially significantly useable for incapacitation spells if they chose to use them. That would seem to be a flavor advantage, but not enough (because of it being combined with fewer spells base) to be overpowering. It also wouldn't make a 1st level slot/spell powerful enough to take down a 10th level character regularly, but would give them potentially 4 spell slots that could be seen as seriously competitive options for expending for an incapacitation spell. And it does seem like there are several effects one might associate with several flavors of Psychics that might have incapacitation effects. Would that be something that could be triggered for spell slots cast while in an 'Amped' mode?
