This is just an idea... for the one half of the thing, make blue fire and for the other half make red fire. just a thought... looks very cool!
it was my first thought, but i know only one model of blue fire, named blue fire, but it's smoke pillar is too high, so i used model fire smal, for all. if you could change origin color in model "fire small", to color such blue fire has, you would be thx much...
Ancient eastern spell, that was firstly used by tibet monks. Creates a great pillar of fire, damaging enemies for 500 hit points. This spell is benevolent to friendly units, making no damage.
