I've been working on a Necromancer (skeleton focus) and have the basics of the book together, and have about 30 spell book points left to spend. I started to think how I could use them to try to have something generally useful in different situations that my opponents might present. For example, I was thinking that a Mage Wand for my limited number of useful arcane incantations, or any of several defensive spells would be nice to have.
What spells would you consider adding that aren't in the usual Necro toolbox? (I already have plenty of creatures, some curses and other enchantments, a few forms of Dark healing, basic equipment, a couple of walls, one Teleport, etc.)
I also am thinking about other out of school things like a damage barrier, Sleep, Banish or Turn to Stone, Push, and an Elemental Wand with a few specialty attack spells (like Geyser for anti-burn use, Flameblast for Plant spells, Surging Wave for anti-Battle Forge use, Chain Lightning for use against Falcon swarms and others).
What would you pack?
