One thing about Crystal Shard- as of Complete Psionic, it now allows Power Resistance to affect it. Seems the designers caught on to this being a little too good somehow.
But it's a shame for your character he didn't get much of a chance to use
Touchsight; both of the Psions in my games have had field days with it- and it can break old-school modules wide open. Example: when I sent the party with the Telepath through the Tomb of Horrors, the recent WotC revision of it, thanks to the Psion (who also had maxed-out ranks in Search and a very high INT thanks to careful choice of race, good stat rolls, and a Headband) the party managed to avoid all of the pit traps and didn't bother exploring past the archways of mist. Secret doors? Take out the "secret" part.
But what really makes the Psion into the ultimate ultility character, I've found, is
Psychic Reformation. If the party has 10 minutes and a few XP to burn, any character can be recustomized to any situation at will. Forget the character rebuilding rules from PHB2, this power lets you repick everything but race and class (well, technically it doesn't say it lets you repick spells learned at level-up, but since it
does let psionicists repick learned powers it's reasonable to conclude that spellcasters should get the same option).
