I've 9 training points left over with my legendary necromaster. But, non-pvp necrmancers don't need as many extra spells as other wizards do. The only non-death school spells I have is ice to tower shield and spirit blades from balance.
I'm tempted to do myth to minotaur and then mutate minotar to death minotaur, which would be helpful for life enemies with death shields but I've Bone Dragon for that.
Plus I don't know what new spells will be added with Winter Tusk and if any will require training points so I'm waiting to see how that goes.
