Reviewing
Ni:
1) At this point, I expect Ni knows if he worships a deity or not, so you should probably update the "Deity" line. Also, you may want to add the Background line to say if Ni's is open/closed/conditional. I added Ni's regional language, too.
2) I added notes about replaced class features in the Class section, mostly because I managed to miss that Summoning Mastery replaces Shield Ally, and had started adding in all the Shield Ally stats.
3) Club melee attacks take Ni's STR penalty on damage - fixed.
4) You still had "Summoner 2" listed in the Skills section, though the total available skill points was right. - fixed
5) Ability mod on Swim was wrong. - fixed.
6) I come up with 369.19 remaining (5 less silver than listed on the sheet), but it's a small enough amount that I'm not especially concerned.
7) Lu still had small quadruped carrying capacity (medium is 1.5x normal) - fixed.
8) Lu wasn't updated with all Ni's languages - fixed.
9) Lu didn't have Evasion listed - fixed.
10) Lu had the wrong size and level listed on his stat block. - fixed
11) Lu's skills still had the old Str mod. - fixed.
The monetary discrepency is minor enough that I don't see a point holding up
APPROVAL for Ni.
I think the only three characters waiting now are two that need fixes and my own, which I can't review. If I missed somebody's give a shout.
