Done and Done. . .
I actually managed to find the plans from Izual on the very next attempt after making that last post, so I think it took me 4 tries in total.
Cavern of Frost was an absolute pain in the ass though, that took me about 3 and a half hours. . . luckily though, because I had to run through the same battlefield area over and over again, I made up the 150k in gold I needed to craft the staff in that area alone.
luckily though you only have to upgrade the staff in latter difficulties, so I never have to go through this process again. . .
Whimsyshire was. . . something. I was surprised that the enemies in it were harder than I thought, however I'm fairly certain you'd understand the fact that there was no way I was going to let myself die to a twinkleroot. . .
