Loving it so far.
I did however notice a typo you may wish to address.
On page 16 under the table and above the dragon the word assess is misspelled humorously.
This is of course meant to be helpful rather than to quibble.
I believe a clarification is needed on page 21 under the heading Action Point Enhancements to the relative to whether enhancements stack and whether or not the must be taken in order.
To wit, at level 3 can I take Extra action point IV or am I required to take I-III? If I take I-IV do I end up with 4 extra action points or 10 (4+3+2+1)
If it isn't too forward
may I suggest changing the table entry as follows:
Extra Action Point I: Base action points are increased by 1
(indent)Extra Action Point II Base action points are increased by 1
et cetera which I believe would solve both problems now they do stack and with the teensy indent they look like you have to take one to take the other.
I believe the confusion stems from the line --but there is no restriction on what enhancements you choose other than your level.
pg 27 Spellcasting: "his spell slots per rest, and the number of spells he may ready each day." I'm confused. Is this an accidental redundancy or is there a daily thing I've missed somewhere with the casters?
pg 36: Combat maneuvers: DO you have to pick _one_ maneuver, or are you allowed to use ony of them when you take "Combat maneuvers"?
Pg 37: It appears as though Monks get up to 4 attacks/round starting at 11. Iterative Attacks (page 19) talks about betting a 2nd Attack at 6th level, and that's it. Does that mean that Monks are the only ones to be able to exceed 2 attacks/round? The final paragraph of the Monk explanation would seem to suggest this, but it might be an idea to call it out explicitly under Iterative Attacks if possible.
Also, the Balance box notes that the centered bonus doesn't grant monks the complete benefits of a full Bab including "the dodge and block bonuses thereof, iterative attack rate, etc." That seems to suggest that the Iterative Attacks should be BaB based, not Level based.
pg 38, Trapfinding: "the monk gains the trapfinding ability. She may use his Disable Device". Should either be "this" or you've got a gender pronoun mismatch. Barb, Bard, are male, Druid, Paladin classes appear to be using female gender pronouns.
pg 45 Familiars: "A sorcerer can manifest his familiar any number of times per day but only up to 1 minute per caster level per rest." The idea of per day and per rest is confusing here.
pg 109 Ability Damaged. This talks about it returning at the rate of 1 per day. I'm not sure if this is supposed to switch to the per rest mechanic, since spells drop off per rest, or if it's supposed to stay 1 per day. If so, it makes Ability damage _much_ nastier in comparison to a lot of other damage. It also seems to be a bit out of step with page 108 Healing Ability Damage.
pg 128 Chart, Features column refers to smite evil 1/day, and others down the entire column. Not sure if this is supposed to be that way or shifted to per "rest" or "encounter" given the nature of the Summon Monster features and the duration of the spell.
pg 138 Disease. "Once per day afterward, he must make a successful Fortitude saving throw to avoid repeated damage." Again, per day.
pg 139 Healing a Diseas: "Characters recover points lost to ability score damage at a rate of 1 per day per ability damaged," Again per day.
pg 155 Empower Spell-like Ability "The creature can use that ability as an empowered spell-
like ability three times per day (or less, if the ability is normally usable only
once or twice per day)." Again per day. Also shows up in Quicken Spell-like Ability.
