You can't really base a character around it. It's only one power.
Solicit the concentration to your psicrystal. Remember to just pump your Int and you can dump Dex fairly safely. Just watch that Ref save. Use
this thread to find ways to gain Int to more modifiers. Faerie Mysteries Init being the strongest, replacing Con with Int for HP. A monk level and Kung Fu Genius will grant you Int to AC again. Maybe even Talasharota(fuck spelling im not even going to try) to advance other Monk features. Someone gaining a Thunder Lance through items would make you even crazier. For the record, don't bother with Swashbuckler. It's not worth it.
Monk 1/Psion 19 (lets be easy)
All the feats listed above. No Thunder Lance.
Int to AC twice.
Int to HP
Int to attack and damage.
20th level Monk features.
Control Body lets you dump Str and Dex. Faerie Mysteries Init lets you dump Con. And no one cares about Wis or Cha. If you want to waste some feats for novelty take Keen Intellect and Insightful Reflexes to truly dump Dex and Wis.
