The necromancer in my group is a cleric so he cannot cast such a spell. But the idea was good, is there a way then for a caracter to learn a single spell from another class ?
I found the undead lord really powerful. The cleric in our group is only level 5 (with undead master and gifted adept feats) and he is able to animate 40HD of creatures (lvl 5 + 4 lvl from undead master + 1 from gifted adept), he is quite op compare to other PCs in the group which is a pain to balance because monsters hard enough for him would one shot other PCs. Is there something we are doing wrong ?
