Enchanter 5 remaining points - INT or STA?

[Xantarr]

Hey all, returning after a long time absent and starting an enchanter (switching from my bard because carpal tunnel). Playing HIE, agnostic, and putting 25 stat points into CHA. Where should the remaining 5 go? All of my reading suggests either INT or STA. I know it's only 5 points but hey. Cheers.
