I'm going for a Petal (MMIII). Namely, I'm basing it off of
this post, which states its racial modifiers and notes that it has DR, flying, and tiny size. It's an LA +2 (cohort), so I figure I would just use the suggestion there and make it into a cohort. Plus, good stat boosts (just shit damage for being tiny). Though, I can see how it can get a nerf, seeing as some of the stat boosts are just damn amazing.
I basically gave it these qualities (based off of the MMIII... not sure if it's entirely correct), feel free to fix if I'm wrong:
Str -6, Dex +10, Con +4, Int +4, Wis +0, Cha +8
DR 5/cold iron
Base speed 15'/60' flying (good)
Tiny Fey
Low-light vision
LA +2
It has sleep-based abilities, but I just didn't care enough to judge whether or not they have it as a racial thing or not. I'm also doing LA buy-off, so it'll be ECL 3 when it joins (for the purposes of a lv 4 cohort at lv 6), one of that being LA. And I used 26 point buy (or whatever it was for elite array).
Rift Magus surprises me with every passing post. That's pretty sweet, really, having a +5 to maneuvers readied. Essentially, we'll have all our maneuvers known readied, correct? (Awesome, I feel like the equivalent to a sorcerer for maneuvers. Not like I know as many maneuvers as the next guy down, but I'm pretty good about it.)
Oh, and question about Feat Rogue: do feat rogue levels count towards being a fighter for the purposes of the weapon focus/spec. trees? Or will I have to pull ranged damage out of my ass without precision-based damage? Or just take a normal Rogue and pray to the feat gods for feats? (Also, removing medium armor proficiency and shield proficiencies (light, heavy) for a fighter bonus feat at lv 3. Or does that get me another one at lv 5?)
And finally, I'll take the crafting up (level 1 to 2). Is there a possibility of making elven leafweave padded armor while making the gun? Also, /facepalm at Max Dex. Thought I'd never have to bother with this pointless statistic... but atm I can't touch a Mythril Chainshirt, much less medium armor (looks like a rogue only loses evasion if I equip medium armor).
