Q is water, and F is fire.
when you use those, they will combine into one element, steam.
therefore: "QF" "QF" "S" "A" "A"
should be, steam, steam, arcane, lightning, lightning.
same goes for Q and R
Q is water, and R is cold, when you use them together they will create another element, ice.
therefore "QR" "QR" "QR" "QR" "D"
should be, ice, ice, ice, ice, earth.
some of the challange maps are really hard, specially the vietnam ones.
EDIT: also, every element has an opposite, for example, earth is opposite to lightning, therefore if you use lighnting, and earth, they will cancel each other out.
