I'm particularly interested in templates, but in general can anyone tell me what playable races and usable templates would grant Powerful Build to a creature? I only know of like, one. The Half-Giant race. I remember coming across others but I can't remember what any of them were.
Half-giant, LA +1 (Expanded Psionics Handbook; stats but not fluff available in SRD)
Goliath, LA +1 (Races of Stone; fluff but not stats available in Races of Stone excerpt)
- Stoneboned, LA +2 (Dragon vol. 350)
Reasonably sure these are the only ones. Of these, the goliath is by-far the best.1
Bonus: the opposite of Powerful Build, Slight Build, is found only in web enhancement kobolds.
1 Half-giants are quite poor for an LA +1 race; aside from slightly higher-than-normal ability scores, they could easily be an LA +0 race. That said, they qualify for the unreasonably-good LA +0 primordial giant template from Secrets of Xen’drik. Combining these results in a race that is almost sorta-kinda worth LA +1?
The goliath is probably still better, though. Especially since primordial tanks a lot of your melee abilities in order to give you superior spell-like ability use, and Powerful Build isn’t really that useful to someone who uses spell-like abilities much.
One "race" to add to your list: Feral Gargun. Also in Races of Stone (pg. 89), they're some sort of "offshoot" of Goliaths (the book glosses over this from what I read) and also have Powerful Build. Unfortunately, they also have +2 LA and 2 starting HD. Not super appealing to most players I know.
I'm assuming large races aren't/weren't an option here. Personally, I'm eyeing a half ogre for the upcoming game I'm playing in, but +2 LA seems like a lot lol
