I know that it isn't the most indicated board to put this question, but the people here are the best, so:
As in D20SRD:
"You can place another power upon your person so that it comes into effect under some condition you dictate when manifesting psionic contingency. The psionic contingency power and the companion power are manifest at the same time. The 10-minute manifesting time is the minimum total for both manifestations; if the companion power has a manifesting time longer than 10 minutes, use that instead. The power to be brought into effect by the psionic contingency must be one that affects your person and be of a power level no higher than one-third your manifester level (rounded down, maximum 6th level)."
Ok. So, when you augment a power, it's level doesn't go up, only some features of it (damage, bonuses). Then, if I'm a 18th level psion I can contingency a vigor power augmented to give me 90 temporary hp (18 pp) when I got myself under 20 hp?
Another question: I can contingency overchanneled powers, ou wild surged ones? If yes, in case of wild surge, you suffer the enervation chance on manifesting the power with the contingency, or when the trigger occurs?
where does it say that the damage & bonuses go up?
you can augment it tho, i guess that's what you mean. yes @ 18th lvl you could contingency 90 temp. hp. (18pp)
yes, there's nothing saying you can't. so with 'overchannel' you could contingency a vigor with 105 temp hp (and take 5d8 hp damage- self defeating) the power & the contingency are both manifest at the same time. so any extra effects of manifesting are incurred immediately.
