Affected spells: retribution strike (depends on your god), insect plague, holy wrath. Those were filling half of the main map with fireballs and lasting quite a long time, producing new fireballs all the time.
About jumping: it was a bug, and has been fixed. It is true that the skills should be more interesting, and that it should be possible to improve skills and not just the stats connected to the skills. If you have ideas about what those skills could be used for and how the skill levelling could be done then please post them (suggestion forum).
