Arcane Atoms: My first thought was that you did not get nearly enough, but then you do multiply by your casting stat, which (I assume you count magic items?) can get pretty high so it should be good
Does using arcane atoms bypass a level cap for damaging spells (So, if I am an 8th level atomosmage can I soup up my searing fireball?) I won't think it would be too bad as blasting (Even though that is a favorite thing to do) is usually seen as suboptimal.
Arcane Sensitivity: Love this, although my OCD makes me point out, your (Ex) should go before the colon; (Ex):
KNowing if an object is magical: So, if I pick up something with GMW on it does it register as a magic object? Also, I would let this apply to effects made from magic, such as a fire wall/of ice (if you don't have DeMa up you technically don't know it is magical :eyeroll:)
MR: well, this is alright but a wizard has a good will save... as do most full-casters (Try to think of one who doesn't, you might beat me
). Immediate action... do you need to use this before you see the outcome of your will save or after, for example:
DM: 'ey youse, make a will save
Player: Alright, [rolls]
DM: Awh, so close, but you needed a 12 not 11.
Player: Actually...
BF: Meh, not gonna kill you, although 1 of them isn't very nice... maybe 2 XD
Bodily Integrity: have some small typing error; "full spell into your body. . You "
I was thinking, for BI and MR Maybe combine them and give them Mettle (per hexblade) activated by spending points? (Then you could work in another feature as well if you combined them like that
)
EC: Nice... although with buffing saves, and everything else I would reduce the cost to 3 points
DtD: Maybe gain some when you cast a spell unaugmented by arcane atoms as well as how it is now?
PP: The problem here is that caster level is (apparently) extremely easy to bump over 60... so maybe level in classes that advance arcane spellcasting (which would still allow UM to qualify twice... hmm.)
Ability Idea: The ability to "steal" atoms from the energy of other mages casting spells. For example if Mr Archmage drops a couple Orb of X you get a few atomos points... I would base the gain rate off... maybe the square root of SL+CL?
the feats:
Atomos Focus: This is better then the feat that gives +4 points, and if playing a game with retraining (and not starting at higher level anyways) then I would start with the +4 (if I needed it) and later retrain for this... I would in fact add:
Special: Upon reaching 8th level this feat may be changed out for Atomos Focus.
to the other for those games that don't use retraining.
Atomos Hoarder: Seems fair enough
AM: Don't have enough experience with psionics
AT: seems alright, not really much going on here, just for the dual casters. Would work nicely in gestalt though.
AC: you give HP 1:1 and I would also say: for every 4 hit points that you grant the creature it gains a +1 enhancement bonus to strength, con, or dexterit at your choice. The effects of this feat stack with themselves.
AN: maybe something like the feats from libris mortis allowing you to add some bonuses to their physical stats? Also, this
should be able to improve turn resistance.
OA: Don't do binding (have the book, haven't had the time to read it) but seems you have a text error; "First, you may when you make a" I would take out the you may, or switch it "First, when you make a binding check you may..."
RA: I would make this points equal to the spell level you dispel, also forgot some other dispel stuff, I would just say spells that
dispel as just in core there is also MD... which most don't use, but it is there... non-core there is dispelling screen off the top of my head.
Very interesting, and the rest of the feats seem to be good.
