I've just done the Spire in one quick run. I fed the Fire Phoenix and the Twilight Phoenix, I planted the Dwarven Armorer and the three military boosters crafted in the MA and quickly went to the Cauldron to get the General's Mayhem effect. The Cauldron took only a minute and I obtained a 10% effect for three and a half hours. There are three hours left, which I won't use because I cater the Tournament (to save time of course).
