Skull trap + Protection from magical energy
This is a combo I learned very recently and I was shocked how effective it is, especially for a sorcerer.
Skull trap has a damage cap of 20d6, compared to 10d6 for Fireball.
PfME will protect your party members from your own skull traps. It has a very long duration, long enough that a sorcerer can easily keep it up on a small party 24/7, without excessive resting.
Combined it wrecks the game. I mean, there are many cheesy tactics, but afaik none of them are so easy to use and require so little preparation. And can be used so early in the game. And I haven't even got Spell Sequencer yet.. oh boy.
