evilin spell help

[Majere3]

I got this spell Evilin. I heard that this is undead rezz spell but I can't seem to get this work. I cast it on the corpse of my dead vamp. The spell didn't turn my vamp back.

I cast it on enemy corpse. It become a cloud of evilin. Then some enemy dragonfly flew into it. It kill some but there are no undead coming back.

Do I need to have full undead army for this spell to work? My army consists of vamp, archmage, inquistors, royal griffion, royal thorn.

No. You need to transform a corpse into evlin and then have one of your own undead troops walk over it. You will get 10/20/30% of the troop back (resurrected). And that indeed is 30% of the whole troop!

Thank you for the explanation. I thought that it was like resurrection spell. It is too bad that my vamp can't get there to resurrected.
