Like the old fart I am, I learned long ago that quicksave is my friend. so, I save before taking/advancing/completing any of the quests. I did the paladin crypt-clearing quest, and saved before completing it. If I kept him alive, he would give me a spell, but it was NOT the Resurrect spell. Like most 'loot' in the game, that scroll is random methinks. My only Resurrect spell so far, I found in Aerie Peak, sitting under a pinetree. Yesterday I went exploring/sneaking through Demonia, and found my long sought-after Sacrifice spell (along with Fire Rain, go figure..) in that castle Nexxy
Happy camper here!
