"Acquire something" is kind of tricky; getting superior gear only does it up to a point, but buying something will do it, too. If you barter with someone with the same need, they'll also get good feelings. "Be extravagant" requires something to be extravagant with, any adorned wearable. Overpaying for something may do it, but that bears confirmation.
That's correct and a great idea, to do this op you have to find people with opposing values then "state your values" and then "acquiesce" in the argument this will cause your values to change.
This gets tricky if you're too persuasive, then it's hard to find anyone who'll counter your statements. You could argue the value and valuelessness of a quality one right after the other and they'll completely acquiesce. This also fails to fulfill "Cause trouble" and "Argue" needs, and leaves no opportunity to practice flattery.
I've so far found a sage and a demon who were firm enough in their opinions that they would consistently oppose. Lacking that, a slightly exploity way is to get into a conversation with an unconscious or mute character, then you can argue back and forth with yourself until you're happy.
EDIT: Found another way to "Aquire" objects: physically yank them from someone's inventory. I assume holding them up by intimidation would work, too. And my "Be extravagant" need was fulfilled by trying on a lower quality item, then swapping it back with the one I already had.
Finally "
Focused!" enough to compose more raunchy poetry! Now I need to set it to a melody and get scantily-clad back-up dancers!
