FYI.. i bought the spell in CR and it wouldnt work so bought it in POK... SK merchant and it worked np... so i dont think the spells work the same ... even thought they are the same spell... i know sounds silly only thing i can think is one is a no drop spell and the other isnt.... how i found out ... first time i did it i bought it in POK but failed ... so i got the pelts and went to CR figured everything i needed was there since i needed to bring up my tailoring.. so bought it off the CR SK/necro merchant and it wouldnt recognize it. so i figured i would try the pok again and it worked
