Revenant Resurrection

To recount from before...

So, your colleague got themselves dead. Not a problem, you've got the coin to donate for a resurrection. Problem is, there's no local temple with a priest powerful enough to raise the dead. And the body is getting a bit ripe.

What about that necromancer? You know, the woman with the unsettling stare and jars of preserved body parts? I'm sure she can do the job. Can't hurt to ask.

“Oh, certainly!” the necromancer says, her eyes scanning your deceased comrade. “Just like those god-fearing clerics do it, just without the pesky religious bits!” She meticulously checks the dead's eyes and wounds. She pokes at fingers and toes with needles seeking galvanic reactions. She accepts the payment.

“Oh, yes, just like the clerics!” She shoos you off, and giggling, retreats with your friend's body into a chamber filled with stinking reagents, clinking glassware, and rattling retorts.

In a week, your comrade is back.

In a manner of speaking.

Revenant Resurrection*

You've been resurrected, untimely ripped from the afterlife via a necromancer's dark magics and possibly alchemical reanimations. You were not called back through the holy powers of a cleric and their congress with the divine. So you may not have gotten back with all of your soul.

You are not quite undead, but you have undead qualities.

The Positive:

• Undead resistances against mental spells and powers.
• You may subsist on half rations.

The Negative:

• Reduce your CON by 1d3 with each revivication. No more revivication at CON <= 3. 
• Having cheated death by these cheaty methods, you lose all divine connection. If you were a priest/cleric/divine class, choose new class (at Level -1).
• That said, no healing by divine methods. Natural healing or potions only.

Them's the breaks.

Oh, and extra rolls on the Reincarnation Side Effect Tables (One, and/or Two).

*This resurrection effect isn't dependent on any specific spell or other methodology, more a thought experiment (and possible flavor) for a PC brought back to life by means other than the divine. Enjoy.

Oh, and Samuel Taylor of 3x5arcana.com made a call-out to my "Build-A-Bear" concept for monster generation in reference to their own 3x5 card-based simplified version. Thanks!
