On the other hand, being able to ignore blasphemy is good too. So maybe soulborn 2/paladin of freedom 3/ranger 2/divine crusader 5/ranger 1/horizon walker 7 to get that and dimension door every 1d4 rounds, leaving my spell in place to give me dimensional jaunt all day long. I could also improve spot and listen, get darkvision, be immune to fatigue and resist exhaustion. I could also get a bonus for hide but in heavy armour that is not so important (but it is part of the forest mastery, there is nothing better to take, and elves like forests). Since caster level is less important here, this frees up the ninth level feat slot. Got it! Put power attack in the level three spot (in case of DR) and move martial study and martial stance to levels 6 and 9.
Hmmm, if I start with a level of Ranger (with the elf subsitution level) I have a *lot* more skill points to play with (32 if INT 10!). This would allow for getting 4 ranks in spot, listen, search, survival, and knowledge (geography), 2 ranks in knowledge (religion), a rank in sense motive, ride, handle animal, knowledge (planes, dungeoneering, nature). Nice broad education. I would eventually max out spot/listen and bring search/survival to 5 ranks, knowledge (geography) up to 8 ranks and sense motive up to 16 ranks (since I am immune to charms/compulsions, it makes thematic sense to try to detect it in others). It is nice that sense motive is a permanent class skill at level 3+. The ranger substitution level modifies the favoured enemy (undead) slightly, giving a +3 bonus to damage and +3 to affecting the spot/listen/hide/move silently/survival checks instead of the usual skills. d6 hd for that level (only) so 4 less hp than if I start with soulborn, but worth it I think. I also start in worse armour proficiency, but the best heavy armour isn't affordable at level 1 in any case. I won't take the elf paladin substitution level because it seems to hurt the smite and I don't need survival to go above 5 ranks, and the default aura of the paladin of freedom seems better. But elf soulborn substitution levels for 1 and 2 are totally worth it. Being immune to charms, compulsions and paralysis is sweet!
So this assumes a 32 point buy for str 18, dex 8, con 14, int 12, wis 8, chr 14 before racial adjustments, then str 20, dex 10, con 12, int 10, wis 8, chr 14 after racial adjustments. Improve str at levels 4+ unless there is a good reason not to.
Interesting that once I hit divine crusader, my aura stacks with previous classes. But paladin of freedom doesn't radiate chaos, so my aura would hit strong in "good" first, then "chaos" a few levels later. I don't think I ever hit overwhelming.
