That sounds really neat, the walking circus.
Meanwhile I abandoned all hopes of roleplaying an Ahmed and am presently having an absolute blast with my Pal 2 / Scaled Fist 1/ Eldritch Scion 2 Aasimar abomination. Next step - Dragon discipling and then I;ll have to decide between another five levels of Eldritch scion v.s 5 lvls of Eldritch Knight or a two-hander specialist for some neat bonuses in power attack mode. Happy in my own skin.
Dragon Disciple suuuucks
Just continue the Scion levels
Hm. Why is that? I plan to reap all the benefits from it: stat bonuses, powers, resistances and then gracefully abuse the transformation spell. What's the chink in my armour?
If you go DD your net spellcasting progression is at -6, so you'll be a 14th level Scion. You won't even get Transformation
Also, 'chink'? Plz don't be racist
Chink - An narrow opening and
vunerable area in one's armor that the opponent will usually aim for. This term relies on "chink" in the sense of "a crack or gap," a meaning dating from about
1400 and used figuratively since the mid-1600s.
As for the rest of your arguments
How on earth will I be a lvl 14 spellcaster? 1 scion spellcasting (second lvl) + 9 DD + 5 lvls of ES or EK. this makes 15 lvls. To cast transfomation I need to be what, lvl 12 spellcaster, no?
As for the rest:
"BAB loss" - First of all, even if I were to continue ES, I d still get medium BABs, second - transformation and other transmutation spells will come to my rescue.
"Spellcasting loss" - only spellcasting I need with this build (I'm wielding twohanders) is a couple of good touch spells for melee opponents (more susceptible to spells than a duelling mage would be) and couple of transmutation cantrips.
"Int and Con useless to Scion" - And? I have minimum int and wisdom and 10 con. So far so good. Pal charisma saves help.
AC doesn't stack with Draconic bloodline AC (or shouldn't) - it does stack alright, and I don't see a reason why it shouldn't - one bonus comes from bloodline, another from being a disciple to a dragon, no? :armenian accent:
"Useless Kn. Arcana requirements" - that much is true. although so far the only useful skill for my dude has been persuasion. happy with that.
"Loss of Scion ability progression" (this alone is huge) - I had a look at those and think there is not much to write home about. by far the most important ability - cast spell & melee hit you get on lvl second and there is no progression for that one. sure, upgrading your weapon is nice but there are other ways of doing that.
