that could actually be fun .... if you buy off the LA you are left with 2 Dragon HD(Full BAB, ALL good saves, good skill points) which make it a Great Psi Gish .... like this:
Pseudodragon 2/ Psion 8/ Slayer 10BAB +16
17th lvl Psion Powers @ 20th lvl Manifester(
Practiced Manifester)
if you also take the Feat
Expanded Knowledge(Compression) .... you could Manifest an Extended Compression(-2 sizes, 40 min Duration) for only 11 PP(17 PP as a Swift action)... then you are Pocket sized .... like a little action figure of a Dragon .... but with a Whole lot of Power
as a Side Note.... you still have all of your Sensory abilities at full range... but now you get +16 to Hide and +4 bonus to Dex(increasing Hide and Boosting AC),+2 Size bonus to Attack and AC.... thus you are very Accurate with Ranged Touch Powers ...... you actually become a Pocket Cannon
