He tries getting a Fox's Cunning, which takes him to +4/+0/+6 (innate +3/+4/+5).
When nothing bad seems to happen to him after a few minutes, he applies an Eagle's Splendour to himself, and takes off the +6 Splendour headband, which takes his stats to 25/20/23.
It... does not appear to send him back to the way he was before... his emotions weaken but do not vanish... so he puts on the +4/+0/+4 headband, before the spells run out, to stabilize his stats at 25/20/23. You can't really get much done with only INT 21, is the problem. He doesn't know, in retrospect, how dath ilani who are only +2sd Intelligence get through life. He sure didn't get far on +0.8sd... well, probably it's that nearly all dath ilani never try to do anything really complicated. Or if they do, they take a lot more time to do it.
And he goes back to work, or tries to. He is still - inside - tired, and the lack of a concrete deadline on how long he needs to keep this up, really is not helping. Especially at only Splendour 23, which, he thinks, is not at all the same thing to a dath ilani, as Splendour 23 is supposed to be to most Golarion natives.
