[@Impaqt] Cho wouldn't actually take being blown up very well. Being made of shadow doesn't mean he's invincible. Treat him like a very tenacious zombie. 

Cho also can regenerate his wounds but if an explosion caused them he'd be out of any fights for a good long while.

I made him unkillable but not invincible just so that I have a reason for him to always be around between fights. XD
