Azure TalentMoI -- Two levels of incarnate and this feat provide up to 4 additional powerpoints (you can only invest an amount of essentia points equal to your class levels in a soulmeld shaping class). As said, this makes a lot of sense if you use psychic warrior as a dip in order to get more powerpoints.
Craft Cognizance Crystal -- This may save you a lot of money and, depending on the campaign, may be needed to actually get a cognizance crystal.
Craft Dorje, Craft Psicrown, Imprint Stone -- Don't take these as a psychic warrior. The main reason why these items are of use to you, is that they can complement your powers known.
Craft Universal Item -- Use this feat to create your own gloves of the titan grip or psychoactive skin of proteus and the likes. If magic/psionic items are easily available in your campaign, this feat becomes almost obsolete.
Earth SenseRoS -- Normally I wouldn't consider this feat, but it's the prerequisite for earth power...
- Earth PowerRoS -- Awesome feat. If you can spare two feat slots you can't go wrong with this. Psychic warriors are starving for powerpoints.
Elan Repletion, EnhancedCP -- Completely unnecessary. You should have 1 spare powerpoint.
Elan Resilience, EnhancedCP -- If you don't want to use share pain and vigor this is an inferior but still nice replacement.
Elan Resistance, EnhancedCP -- A +4 racial bonus on all your saves is already extremely strong, with this feat you should be set for life as regards saving throws.
Elan Retainment, EnhancedCP -- Once per day and the cost of 3 powerpoints make this feat mediocre (at best) instead of great.
Expanded KnowledgeSRD -- Use this to pick up powers like share pain, metamorphosis, schism and anticipatory strike. Prepare to feel dirty, though.
Extend PowerSRD -- Very good feat which can really help with powers which last 10min/lvl.
Heavy Armor OptimizationRoS -- Forget about this feat (although it's still way better than dodge), it's a prerequisite for...
- Deflective ArmorRoS -- Lets you add your armor bonus (including the enhancement bonus) to your touch AC as long as you're psionically focused. Great feat.
Instant ClarityToB -- If you've already taken psychic renewal you probably should select this feat. But also in general, after you've dipped into a martial class, this feat can be very nice if you frequently use a mechanic which demands that you drop your psionic focus.
Kalashtar Mindlink -- Mindlink is a very useful power, and if you like to use it, then this feat is really good. Only for kalashtars, of course.
Linked PowerCP -- Great feat for psychic warriors, because buffing takes so much time. Try to take this. There is a cheesy combo which lets you reduce a power's manifesting time: Since linked power works completely independent from the power linked to the one you actually manifest, you can, for example, link psychic reformation (10 minutes manifesting time) to expansion and manifest both as a standard action.
MetapowerCP -- Use this with a power you're in love with and use frequently. Has the potential to save a lot of powerpoints.
Midnight AugmentationMoI -- This provides access to augment options beyond your current level.
Opportunity PowerSRD -- Use this with dissipating/dissolving touch and hostile empathic transfer. Good for masochistic builds (combat reflexes, karmic strike, robilar's gambit), otherwise skip it.
OverchannelSRD -- Not bad for getting more out of your powers. Only use it with the talented feat.
- TalentedSRD -- This makes overchannel usable.
Practiced ManifesterCP -- If you lose manifester levels this becomes a great feat. Tashalatora builds must take this, if you go the slayer or sanctified mind route consider it.
Psicrystal AffinitySRD -- See
chapter VI.
- Psicrystal ContainmentSRD -- See chapter VI.
- Psycarnum CrystalMoI -- If you already have a psicrystal and the azure talent and midnight augmentation feats, this feat does make a lot of sense. Also helps the incarnum infusion power.
Psionic Fist/WeaponSRD -- A prerequisite for greater psionic fist/weapon and deep impact/unavoidable strike respectively.
- Deep ImpactSRD -- Expend your psionic focus to make an attack as a touch attack. This can be very helpful. Combined with hustle, you can do this over and over again.
- Greater Psionic Fist/WeaponSRD -- Combine this with hustle.
- Unavoidable StrikeSRD -- See deep impact.
Psionic BodySRD -- This feat may help in the early levels, but since you won't pick up 10 psionic feats, improved toughness will be better.
Psionic MeditationSRD -- Regaining your psionic focus as a move action is great, since you can use hustle to do it as a swift action. Mandatory for some builds and a very solid selection in any case.
Psionic TalentSRD -- Contrary to common belief this feat does not stack with itself and thus, is is not worth it. In a strictly low level campaign it may be worth taking it once.
Psycarnum InfusionMoI -- Pretty useless if you only take a few levels in a soulmeld class. The possible effect can be quite powerful, though.
Psychic RenewalToB -- If you've accessed a maneuver via martial study, you can use this feat to recover the maneuver in combat. Even if you do have a recovery mechanic it may come in useful. All in all this sounds very nice, but the cost in powerpoints is probably too much.
Speed of ThoughtSRD -- Cool feat. I like movement speed. Meshes very well with the hustle power. If you've got an open feat slot, pick this up.
- Psionic ChargeSRD -- Only for charging builds, but for a charger this can be extremely helpful. But you must expend your psionic focus and have line of sight to your target.
Synad Multitask, EnhancedCP -- Only for synads, of course, but for them it's nearly compelling.
Tap MantleCP -- This gives you the option of picking up more mantles after you've taken the mantled warrior ACF. You do not gain the mantle's special ability, but the access to multiple powers not on your list can be very much worth it. As an example, if you have taken the freedom mantle with the ACF, you can get this feat for the time mantle and select anticipatory strike and temporal acceleration as powers known later on. Don't take this feat if you need only one power from the mantle's list and do not care that you get it later, in such a case expanded knowledge is infinitely better, since you automatically add the power to your powers known list.
- Don MantleCP -- Some of the granted abilities are really, really good and if you've already taken tap mantle this feat can make a lot of sense.
Up the WallsSRD -- Neat but not worth it. If you like the style and have an open feat slot, you can go for it. The wall walker power is infinitely better though.
Quicken PowerSRD -- As quicken spell, this feat lets you use a power, with a manifesting time of 1 full-round action or less, as a swift action. Great for psychic warriors since they are extremely "action-starved" due to buffing. The reason why i've colored it in green is its cost: An additional 6 powerpoints really is a lot. If you use it frequently you will burn your powerpoints way too fast. For psychic warriors this feat comes into equation at eleventh level at the earliest, probably later.
