If you go by it's "original" stats it's a advanced assault fighter..
4 guns (2 banks) and 2 missile banks, better speed and maunverbailtiy than the Herc2, but mediocre shield and armor. Doesn't sound impressive, no? The trick is the ship auto-repairs it's hull and if you have a SPC build (_SHD build methinks) that supports the two ships.tbl entries I added above it will re-charge shield and weapons at an alarming rate too

Makes it hard to kill, as you either have to hit it with a huge amount of damage instantly or keep him under a constant barrage - if he escapes by the time you aquire him again his shield will allready be re-charged. The weapon re-charge means it can carry really heavy stuff like Kaysers and not worry about power.
Leave it without shields and with 2% hull and it's will be back soon, fully repaired and ready to blast ya...basicly coming back from the dead, thus it's name.
