Some time ago i readed on this messageboards (and that was stated by James Jacobs in one of many theards about simulacrum spell )"Nope. Fast healing (and regeneration) are both "healing effects" and thus don't work"
My Question 1) is : if this statement is correct soooo Vampire should not have Fast Healing yes ?
Well... JJ's statement was his own opinion of course, and not an actual game rule. But it does make sense.So yes: Simulacrum Vampires get no Fast Healing.
2) what would happen to mr.SnowPire (Vampire) after his hp = 0 ?Vampires dont die on 0hp they change in to "smoke" form and go back to coffins and after 1 hour they gain fast healing but problem is...
our Vampire dont have fast healing....
- Vampires turn into smoke at 0 HP.
- Simulacra turn into a puddle of water at 0 HP.
- And so: Simulacrum Vampires either turn into a puddle, or turn into smoke which then turns into a puddle (since the Vampire is still at 0 HP).
should i restore temporaly his Fast healing (or dont delete it at all) ability or let him rot in coffin in gasesous form ?
If you give the Vampire his Fast Healing back, he could simply "kill" himself after a fight in order to regain all health. A Simulacrum should not be able to heal like that - it's one of their main drawbacks.
or let my player use simulacrum implemented repairing methods on body in coffin ?
What body? Simulacra leave no body once they're at 0 HP.
Last Question :would negative energy in this case count as "healing effect" for snowy vampire ?
Yes, it would. It gives the creature HitPoints back, so it's a "healing effect". The Make Whole spell wouldn't work on the Simulacrum of a Construct either.
