I've never had any trouble with Liquid Flame at all.
I'd suggest using a Time Mage, Black Mage, Summoner and Mystic Knight. Have your Time Mage cast Gravity, your Black Mage cast Blizzara, your Summoner cast Shiva and your Mystic Knight use Blizzara Spellblade.
u need 3 knights(or any other heavy-hitters), a mage that can use rods, and a frost rod. break the rod (select from items, place in hand, then proceed to keep pressing A) then thwack him with ur knights. easy-peasy, lemon-squeezy!
ive got black magic, a hair trigger, and a short fuse. bring it!
