Just chose to learn Tactical Pyre, and did a CTD. Running WinXP, DoD on Steam. Using the hotfix for mysterious portals, quest hordes, and crashes (ironically) post level 1.
Second time around, the spell was learned without problems. Damn. I was hoping it was a reproduceable bug.
Can you remember if the monster which triggered the level up died a) in a damage field, and b) when you were moving?
Damage field, I'm pretty sure. I'm running a pyromancer/psionicist/blood mage, and had opened a zoo. Ran down a couple of rooms, settled back, and shot off plenty of pyrokinetic attacks. Does that matter?
