OTOH, how do you skill spells on a Wizard? What do you skip/use, from starting book, at least?
I tend to learn everything from the starting book, and later ditch slow and summon imp.
I usually start out skilling spellcasting and conjuration.
The main tactic I like to use is hiding in a corridor and using conjure flame as a barrier. If there is no room for conjure flame, you can summon imp, back up twice, and then conjure.
Summon imp is a pretty good spell for a while actually.
Mephitic cloud is also very useful to deal with crowds, especially if your character doesn't breathe like my current grey draconian.
Blink is used to escape, magic missile for killing the basic enemies.
I base my later skills off what books I find/are given.
I haven't gotten past the area called "Dungeon" T_T
How far do you usually get to and what kills you? (Like, which level of the dungeon do you die on)
Have you reached the ecumenical temple?
You probably need to use the tactic called "Running for your life" a little more often.
