To clarify a bit more, the issue specifically seems to be that attack power of spells is scaling much more quickly than monster health as you move up tiers. I think monster attack power vs. player health is probably okay.
Thanks for the clarificaton. That's what I had assumed, but, it's nice having confirmation. I think the easiest thing to do programatically is to up how fast monster health scales.
Question for you 1.) Do you have a world that you've played pretty deep in that you've got saved? If so, could you send me your WorldEventLog.txt file from that world? Misery, if you have one, or more than one, that would be great.
If you don't have that, could you at least tell me what difficulty you are playing on?
Thanks!
