Ok, psionic powers have no verbal or somatic components, but they do have wierd displays, if the psion is not careful to suppress them.
The ability I am using
Attraction only has an auditory display, but I'm not going to draw attention to myself by letting that noise go off.
The psionic focus I
concentrated to gain this morning allows me to use my other psionic feat to run
Up the Walls as long as I stay focused. However, I'm going to temporarily forsake that ability, and instead expend my focus on giving myself an automatic 15 as my "roll" on the concentration check to avoid making any kind of display. (See the psionic concentration skill linked above).
As the DC to avoid making a display is only 15+power level, and her concentration bonus is significantly more than 1, this gaurantees an unobtrusive casting.
As for the power of the casting, the normal DC would be 10+power level+her int mod of 4. I'm also going to spend 3 pp instead of just 1, casting the most powerful effect I can (pp=manifester level) to raise the DC and effect by 1.
So she is strongly attracted to the memorial for the next 3 hours unless she makes a DC16 will save.
FYI - this reduces my remaining PP for the day to 5 I believe. At least my myth weaver sheet has said 8 for the past couple months. :)
