What spells do you go for as a wizard?

[Nitrous]

staff of cthulhu? staff of lazarus? What do these spells do? I don't think they ever got mentioned in the wiki..

Also, in my ( brief) experience as a wizards, cyborgs are a major pain and invulnerable to most spells. What is the best way to get rid of them?

They are not spells, they are staffs.
The staff of cthulhu for example makes corruption faster, aswell as more brute damage than the regular staff. Also, knock is a good spell against cyborgs, that is, if you can get close enough.
