If that's the case, and divine champion still gets his usual bonus feats, then we have instead
Level 8-12 as divine champion:
2 feats from the PotM system for lvl 2 and 5, and 2 more from vanilla nwn for lvl 2 and 4, totalling 4.
So that's just one less, or 12 feats. If he doesn't get the vanilla feats, it's 10. Maybe someone that actually played the class here can tell which it is.
