Changes

The skill is taught by [[Jumjab]], a goblin in southwest [[Eltibule]] by the Kur portal. You will need to speak Goblinese, get his favor to Friendly, and have Necromancy of at least level 20 before he will offer to teach you for 1000 coins.  It seems you will then need to do the 8 hours hang out with him before you can talk to corpses.
