I am utterly convinced that the lightning mace is programmed to be a Murphy's Law weapon. It should be a good crowd-control spell, and the target is supposed to be random, but if there is one enemy in front and the rest grouped in back, it hits the single enemy, and if there is a mob beating down your front line and a single archer in back, again, it hits the single enemy.
...Then again, I just lost the Mastermind game a couple hours ago because my minions failed missions over 10 times in a row. Perhaps I have just pissed off Lady Luck today for some reason.
My minions (and patsies) are idiots. They failed 12 missions in a row, despite a 70-90% success chance each time, until I ran out of money. Shitty luck can kill you in this game.
