The general consensus around the forums seems to be that the Child of Acavna and Amaznen (CA&A) is just a watered down Bloodrager. That opinion, I think, is not egregiously wrong, but it fails to recognize that they have very different strengths. I would argue that the CA&A has a few unique characteristics that make it worthwhile and an incredibly interesting chassis on which to build a true Tank Caster rather than the Bloodrager's Smash Caster:
1 - As far as I can figure, it is the only other full caster level and full BAB class in the game without the need for traits, racial abilities, or feats. Straight up full CL and full BAB.
Besides Arcane Strike, can anyone think of other feats that scale with CL or BAB that would benefit the other discipline? (A CL scaling feat that benefits melee, or a BAB scaling feat that benefits spellcasting)
2 - A CA&A has full Armor Training and does not lose Advanced Armor Training. Therefore, the CA&A has the potential to quite easily pump up AC and the various defensive benefits of Advanced Armor Training. Thanks to Advanced Armor Training, the CA&A gets the AC of a normal fighter PLUS the DR of a barbarian, while a bloodrager must choose either heavy armor (Steelblood) or DR.
So the rules question is, am I reading this correctly that armor training is just modified to add arcane spell failure reduction and therefore advanced armor training remains unchanged? It ONLY talks about adding a benefit - it makes no mention of changing any other aspect. I think I'm reading this correctly.
3 - A CA&A is a prepared caster meaning its spell casting is far more versatile. This is a bit of a push - some people prefer spontaneous, but I like the versatility.
4 - Combat Expertise is no barrier. I don't really love combat maneuvers, but all those things blocked by Combat Expertise become a bit more palatable as you are already invested in Int.
Thinking about these things, I've found a few synergies that I'm toying with for a build:
Arcane Strike + Bodyguard + Gloves of Arcane Striking makes way more sense here than on a Bloodrager. An AOO that scales, increasing an adjacent ally's AC by 2 + 1 per 5 levels. While a bloodrager can do this as well, they can't avoid a hit like a CA&A can. In other words, disincentivizing hitting allies is disproportionately more beneficial to the CA&A because the CA&A ALSO is a tough target to hit. The monster is unlikely to hit the ally, but also unlikely to hit the CA&A. On the other hand, the Bloodrager is just absorbing damage (necessitating healing/resources later).
Crafting Magic Arms/Armor (or maybe Wondrous Items). Prepared casters are just better at crafting because they don't have to waste a spell "known" on something they only need for a crafting check. Fighters are extremely item dependent, and this overcomes that issue without the need for the Master Craftsman investment. (The advanced armor craftsman option only works for armor.)
(Just like a bloodrager) Can self enlarge person, but can also easily craft an impact weapon for himself (Unlike a bloodrager).
Kirin Strike/Style is a natural fit - adding Int x 2 as damage (In addition to your strength). Outpaces Bloodrage damage bonuses.
Fighter Only Feats (Or early entry for fighters): Great Weapon Focus/Penetrating Strike/Etc.
Can anyone think of any other good synergies?
Hurdles:
A - Feat Loss. Still the same number as a Ranger or Bloodrager, but can be any combat feat (Not limited by bloodline or combat style lists).
B - Two Handed Martial Proficiency. Easily overcome with Half-Elf or Half-Orc racial proficiency (Or Human Bonus Feat). Or just use a longsword in two hands.
C - Early level Arcane Failure. This is just a matter of time until you can afford mithral around level 7.
D - MAD. It's slightly better than a Bloodrager because CHA is a far more palatable dump stat than INT or WIS.
Am I wrong here? Does this spark any other build ideas for this unloved underdog archetype?
