Bugs/Glitches and other Strangeness (useful or funny)

I'm just wondering what strange occurrences people have encountered in the game (I'm going to make another thread for annoying ones too) this is for ones that are either useful or funny.

My useful glitches

I had a wizard who for some reason got a several increases in dexterity for no apparent reason. She ended up with a dexterity of 210!
The effect of this was that she was almost untouchable in combat as her AC was ridiculously high and was guaranteed first strike in a round. This meant that she was able to foil the attack by the

by dropping a maximised fireball (as I recall) on them.

I also found in one game that after my clerics had used Righteous Might they retained the reach of an enlarged creature for the rest of the game, which was nice!

 

There are some pretty funny glitches posted in the "I didn't know I could do this until now" thread.

I personally have yet to be granted the 210 dex glitch, which would be pretty nice.
