So, here I am browsing the PHB3, and I find myself thinking the ardent might be fun. I look for a race to go with, and half-elves fit perfectly. I then remember the dilettante racial feature, which causes me to go back to PHB3 and look at the battlemind's at-wills.
And now I have a question. Could, say, a half-elf ardent who chose a battlemind/psion power as their dilettante power use their power points to augment it? I haven't by any means read PHB3 cover to cover, but I haven't noticed anything so far that would prevent this.
EDIT: I just found my answer, haha. Under "Power Points" in the ardent, battlemind, and psion class descriptions it says: "You can use your power points to augment any augmentable power you have, regardless of how you gained the power." So, if anyone else was wondering, there's your answer
At least they've already fixed it so you can't choose a 27th-level at-will for your dilettante power
