ShurikVch made a thread exploring possibilities of this template: https://forums.giantitp.com/showthre...rit&p=25188031

It was concluded you really need to jump through hoops to make it remotely effective at doing much of anything, and even then, there are a few ways the RAW can be read on it's action and attack limitations.

All in all, I'm inclined to rate this LA -0. Being incorporeal is nice, as is a chance to auto return after being destroyed, but there are better and far more effective ways of getting both. This template just has too many inbuilt drawbacks...
