Another option
Another option is allow the 3 characters to go a level or two above what the module calls for. This give them the extra power boost that they might need to get around things.
Both Complete Adventurer and Complete Warrior have some really good stuff in them. Most notably from the top of my head is the hexblade from Complete Warrior and the shadowmind from Complete Adventurer. If you have evil psionic halflings you may want to look at the shadowmind class more closely...
Actually the Maximize SLA requires a spell-like ability at caster level 6 so the character could have it if they took it a 6th level without taking Improved Flight or the Extra Invocation feats. ;) Maximize SLA is in Complete Arcane. As for the blast invocations there can only be one eldritch...

The thing that really brought this to life for me is my two NPC's that I am about to throw at my characters. They are both 15th level Masters of the Unseen Hand. The save on their telekinesis spell is a 23. For most parties that would be a decent save to try to make but it doesn't seem so with...
Ah Ha!!
Ah ha! Ok... how about this?
Maddening Babble: The muttering and chattering of the skulls confuses anyone trapped in their midst. Any creature caught within the swarm at the beginning of their turn must make a Will save (DC 20) or be affected by the confusion spell. DC is Charisma based.
I'm starting to run into a problem with my higher level party. Their saves are outpacing my NPC's save DC's. Most of the characters are 14th-15th level. They are also all experienced players. They make DC 23-25 saves most of the time with little difficulty.
