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?

Potions for pickpocketing are everything.

Early game I often try to drink some potions which enhance my pickpocketing abilities and just go around town picking everyones pockets. It gets me some gems or gold from nobles, some gold from commoners, and atkathlan guards or soldiers sometimes provide magic scrolls such as protection from magical weapons, true sight, minor spell turning or mislead (no idea why those particularly).
It gets you some nice cash for early items, as well as some nice early scrolls which may be useful in your adventures.

There are only a few important NPCs which you can pickpocket which normally have some nice items (riblad has a ring of regeneration or something alike in vanilla, but in Anvil it has been removed).
