Interesting tactics, good combos Options

[Shadan]

Although most of us thinks ourselves as a good and clever player, I think it would be good to write down interesting tactics, good combos. Atleast myself enjoy to read these kind of posts.
That Spider Spawn+Web for example was interesting for me, because I haven't thought those summoned spiders are immune to Web. Of course I used usual: Greater Malison + Web, + Entangle + Stinking Cloud combo and ensured my kill with some Fireball, Cloudkill etc.
Another interesting thing was for me that Sunfire bypass through magic resistance. Is this right?

I always liked this spell page by Xyx. Several spell uses which I had never thought of, combinations, which spells counter which, etcetera.

Of course, Sikret has made some spell changes, but in theory you can get a lot of ideas from there.
