1. The 'ideal' Truenamer; and Illumian member of the Paragnostic Assembly with an Item Familiar, and the 'optimal' selection of utterances.
2. A "solid" Truenamer gish, busting out the Knowledge Devotion and... other things. Slightly less optimized for pure Truespeak, perhaps.
3. A Truenamer who can do more than Truename; a Raptoran Dragonborn with Soulmelds or somesuch thing.
4. A good gestalt build, or several. We could even bust out a Shadowcaster Truenamer, which would be awesome.
