I am basing this partially on The Court of Owls from a recent Batman comic run. So possible spoilers if you read Batman and haven't finished the Court of Owls story line.
The assassins are called Talons and they are trained from a very young age and once they pass the trials to become a Talon they undergo a procedure that turns them undead. They feel no pain, all of their wounds heal. Even a head will reattach to its body if left near by. The only way to stop them is to freeze them, but as soon as they thaw they will start to regenerate.
Their weapon of choice are throwing knives which are all poisoned with a paralyzing agent. In fights they usually end up stabbing upwards of 10 into their victim during the fight.
I basically want to recreate them in pathfinder as opponents for my party which is currently APL 4. I can scale them up later but 2 should be a tough fight with 4 or 5 being a "We need to run" situation. I was thinking of just building them as NPC with 3 Rogue class levels. Taking TWF, Quick Draw, and Weapon Focus (dagger). I'm unsure as to how to handle the regeneration, maybe Fast Healing/3ish. Or what poison to use, I want the players to be able to be poisoned and feel like their character is getting weaker. But I want to make sure it doesn't feel like Save or Die.
Any advice or thoughts would be great.
