Game Mechanics: Undead do not train

[Nirgon]

Yes specters did gate low hp. They didn't announce it like, say frogs in seb or raid mobs either.

I remember getting them low, not having the mana to finish right when I triggered "gate hp" on them.

The specter would gate back to its spawn point, but not immediately aggro. However, if you got close enough to the island/its spawn point again, it would start chasing you again (bringing his friends along too if any were up and the # aggrod was affected by your level) and would slowly regenerate its hp and if it had been disengaged until then.

Fact! Not fiction!

What a fun memory to have right there.
