When you consider the cost reductions that I have, it's not so clear anymore.
Anyway, like I said earlier, this is good because it's the knowledge that would be next to impossible to obtain without experimenting first.
In the essence of it:
final_cost = base * Max (0.5, x1*x2*x3*x4*x5)*(y1*y2); (it's crude summarization Adom handles it in complicated way)
In which x1, y1 etc are modifiers.
I think it is mostly known that almost all modifiers go through comparing vs 0.5, except of bookcasting (otherwise wizards would cancel out it through knowledge and class powers) and charging room (that is probably bug).
If you ever tried cost Acid ball like at 80 spell points with lv50 wizard who has reasonable knowledge of it, you would notice that cost is actually not mounting (probably, it's been a while since I had lv50 wizard).
So far rolled 15 casters with RoDS and shamelessly killed them within 200 turns. For eternium glory!
(after 15 I stopped counting...)
