As far as I can tell, you can't search by monster category, unfortunately. I can grep protos.tab, though. Category 2 is the hardest, because there's no particular marker (I think) for them. I think drow should go in there, for instance. Combing through all 3,000+ creatures doesn't sound fun, though. I have seen that. I was kind of hoping to not have to learn it quite yet. I guess I'll have to bug Shiningted about getting the particle viewer.
I think there is a particle effect for sunburst, I used it in the Juggernaut's death sequence. Though, judging by its name, perhaps the author wasn't pleased with it. Code: game.particles( "Ass Sunburst" , attachee)
I did see that, but I thought it was a joke or something. Having looked at it, it's way too small. The radius on sunburst is absurd. 80 feet. It covers more area than can be displayed in 800x600 (in fact, at that resolution, it's difficult to position the mouse so that you see the edge of the area of effect).
Bah! I just discovered a major snag in enervation/energy drain. Apparently, when deciding if you die from level drain, the game only takes negative levels and class levels into account! This means that even a single negative level will instant kill the balor guardian. I doubt there's any way to fix this outside of a serious DLL hack, so those two spells are down the tubes.
