In an upcoming game, I'm going to play a psion who only participates in combat through his psicrystal. My DM likes the concept, and he's willing to give me some leeway on the rules to make it work - he'll be ok with extending the range of Share Powers and Deliver Touch Power to something more practical, and I'll probably be allowed to take some cross-class powers in exchange for not taking any powers with range other than personal or touch. The campaign will be using mostly Pathfinder rules (which means more feats for Improved Psicrystal and I don't have to worry about class skills, but Metamorphosis is nerfed), but I'll be allowed to use almost any source as long as it's not too cheesy. I have no idea what the starting level is going to be, but the plan is to go to at least level 20.
I've reread the original The Big Guy Is With Me thread for ideas. I couldn't find blingy anywhere, and I seem to remember there being a psicrystal build in the 100^10 challenge, but that also seems to have been lost to the Wizards forum black hole. Any other reference threads would be appreciated.
I'm thinking the psion's feats will just be Psicrystal Affinity, Item Familiar (if allowed), and a bunch of Improved Psicrystal. All the psicrystal personalities will be Friendly, and I'll be the diplomacy monkey outside of combat.
For the psicrystal's feats, I have:
Weapon Finesse
Martial Study (Shadow Blade Technique)
Shadow Blade
Deadly Defense
Giantbane
Martial Stance (Assassin's Stance)
Underfoot Combat
Confound the Big Folk
Combat Expertise
Improved Trip
That takes me up to level 19 under pathfinder rules, so I can fit in 7 more feats pre-epic if I don't change the psion's feats. Any suggestions? I was thinking maybe another Martial Study at the end (could get an 8th level maneuver). Are there any epic feats worth taking?
For the psion's powers, I was thinking about these:
Vigor
Metamorphosis, Minor
Claws of the Beast
Biofeedback
Prescience, Offensive
Painful Strike
Reconstruction
P. Lion's Charge
Hustle
Metamorphosis
Empathic Transfer, Hostile
Animal Affinity
Prowess
Claw of Energy
Broker
Truevenom
Compression
Psychofeedback
Form of Doom
Temporal Acceleration
Metamorphosis, Major
Fission
Combat Transformation
Cleanse Spirit
Trigger Power
Metamorphosis, True
Timeless Body
Assimilate
That still leaves me with a few power slots open - am I missing any useful powers?
With this setup, my psicrystal would be using his tactical feats to trip the enemy and getting a good number of attacks per round, but his damage output wouldn't be that impressive.
