Puzzle... ..Want to help me?

Hi.... I am doing a "elements" map and i would need some good ideas to make puzzles.. (and maybe also trigger help).. I got bad fantasy so i want you to give me ideas.. I would also like if you have ideas for puzzles that have with earth, water, wind or fire to do...

Thanks...

For fire take advantage of the Fire trap and fire side drap doodads, pretty easy to link a trigger to when a unit gets caught in the fire. Same with water

For earth basically any special effect, like try reach acros to some point but avoid the earthquakes or volcanoes

I'm making an Elements map too, but with more similarities towards footwars.

I dont have any real suggestions, but make it at least obvious in one puzzle that all elements are in perfect balance. Fire -> wood, wood -> earth, earth -> water, water -> fire. Etcetera.

Thanks ^_^

I will now try to fix different armor types and damage types...
And also give you guys a small credit.. Even if i doesn't use this things. (but i think i will)

:( but one thing make me wonder: what is the elements? some people says it is earth, fire and water.... other says it is earth, wind, water and fire... ..other says that it is ice, fire, earth, light, water and wind..... and much more... I am using earth, fire, water and wind....
