Spellshape Auras: How do these work from multiple sources? An Anchorite 1/Spellshape Paragon 1/Shaman of the Elements 4 has it from 3 different sources. Does that mean 3 auras at once?
Anchorite:
I missed this before, but the auras each have nice basic effects in addition to scaling bonuses.
Also, this should say somewhere that you can only project one aura at once before 10th.
Feats:
Not sure how I feel about Metashaping feats. Without Metashaping Mastery, you have a good chance of failure, lost actions, and nonlethal damage even on things with effective levels a few below your max level.
Chain Spellshape - Keep the 7th level+ penalty as dazing, not stunning. Stun immunity is easier to come by than daze immunity, like from Elemental Adept 10, for instance.
When shaping a chained melee spellshape (or channeled through a melee weapon), the ranged touch attacks for secondary targets might make you provoke an AoO. I'm not sure exactly, because I can never remember exactly what the rules on AoOs for ranged attacks are, nor how the usual wording for no provoking AoOs for SLAs that melee spellshapers use goes.
The example is incorrect. The DC only drops by 2, not 4 (secondary DC 15 not 13).
Enhanced Formula - Do you still have to make shaper level checks to use the metashaped formula? If so, this feat is strictly worse than just applying the metashaping feat manually.
Mastered Formula - Should recover it either:
a) 5 rounds after you
last shaped it, or
b) after it has been expended for at least 5 rounds.
As written, if you shape it, recover it, and then shape it again, you'll recover it twice (once 5 rounds after the first shaping, and again after the 2nd one). If you start spamming it over and over, you can eventually be recovering it every single round. Probably not intended. The above suggestions will change it so you lose the pending recoveries if you recover the formula sooner (a, b), and if it is expended without being shaped (b).
Maximize Formula - Large amounts of bonus damage instead of large dice may make failing a 4th level metashape more dangerous than at 7th level one.
Metashaping Mastery - Since you take 10 like a skill check, you still can't take 10 in combat (or other stressful/distracting situations), the main time when you'd want to other than with Persistent Spellshape. Just needs to add the "even while threatened or distracted" clause.
Mobile Shaper - Shot on the Run for spellshapes? Precise Shaper is a wasted feat for characters who want this for use for melee spellshapes (using it as Spring Attack). Speaking of which, you might want to let Mobile Shaper count as Shot on the Run, Mobile Caster, and/or Spring Attack for prerequisites and other options. Just a thought.
Persistent Formula - 10 minute duration is well enough for something with encounter-period recovery. Might be a bit tedious keeping it up all day, though. Maybe make it 24 hours, but dismissible if you need to get the formula back or change which formula you persisted? Or is this part of the balancing to prevent someone from persisting formulae they can't always succeed on the shaper level check for?
Just a thought, how about letting a shaper take the feat multiple times, each time letting you persist another formula at the same time?
Sculpt Spellshape - How does this interact with a Spellshape Champion's channeled spellshape? Forget Spellshape Study for a ranged shape, I'm taking this 1st degree metashape to make my melee attacks AoEs.
Shaper's Stride - This is bloody cool.
Spellshape Aura - How does this interact with already being able to project a Spellshape Aura? Similar to Anchorite and Shaman of the Elements, shouldn't this be a full-round action to project?
Still Spellshape - How would this work with a channeled spellshape? I hit you with my sword without moving.
I think your Aging table is incorrect. It looks like a copy/paste of the starting age table.
How is an aging table capable of being incorrect, exactly? I based it off of the aging rates of other races, yes, but that's mainly because I didn't want to just pull numbers of of thin air.
For most aging tables, the age for each category is fixed, with only the maximum life span being variable.
Since the numbers on starting age and age categories are copied, funky things happen. Adulthood (the time between the start of adulthood and the start of middle age) is 0 years. Anyone playing a character with a late starting age (Wizard, etc.) has a decent chance to be beyond their maximum age, dying years before character creation.
The longest lived Caymir (Adulthood 18 yrs, similar to humans) has a maximum age of 18+6+12+18 = 54, which seems a bit short, no? Masked Ones are 15+4+6+12=37, Stoichen are 20+12+18+24=74. I think only Azurin have similarly short lifespans compared to starting age, and that's part of their racial fluff (born with essentia but the incarnum energy eats their bodies up, burning through their lifespan quickly).
Edit: A couple typos I noticed.
