Vampires:
- You are undead, so you get benefits such as not needing air, but you still need your brain to survive.
- Double speed, strength, and damage reduction.
- Immunity to were-creature bites.
- Physical attributes locked in place.
Necromancer:
- You are still living, though immortal. You need your air, blood, brain, etc. (UNLESS COMBINED WITH VAMPIRE)
- Zombie pets! (a game-breaker ability if you animate powerful enemies)
- Physical attributes locked in place.
Were-creature:
- You are still living, and mostly mortal/normal. You still need to eat/drink/sleep.
- Your strengths and weaknesses kick in once a month (otherwise a normal dude)
- Strength, speed, immunities, doesn't need air, trapavoid, contagious bite, glowing eyes, etc. when transformed
- Weapon material weakness when transformed
- Legendary+5 stealth when transformed
- Immunity to vampire blood.
- When you transform, you regain all missing limbs and heal all injuries, but you drop all your items.
Thrall/husk/zombie/etc. of the mist/cloud/murk/etc.:
- Completely undead (ageless, don't need air/food/water/sleep/etc.)
- You can see without your eyes.
- You move slower than normal.
- Triple strength and toughness.
- You no longer need your brain, spine, or nerves to move around.
- Physical attributes locked in place.
- All living creatures are hostile to you.
I know you can become a vampire necromancer. Perhaps you can add husk on top of that to become more powerful.
I read that if a were-creature is chopped into bits, the necromancer-animated body parts will regenerate into were-creature clones and then change back later into fully-healed zombies.
