Merge Elements

Combine 3 or more elements to change it into the next element in the cycle. Plants burn to make fire. Fire burns reducing everything to ash (earth). Earth permafrosts creating ice. Ice melts into water. and Water nourishes the plants. When merging elements, the last tile dragged will destroy the tiles around it that have an elemental weakness. Fire burns plants and melts ice. Earth smothers fire and dams water. Ice cracks earth and frosts plants. water melts ice and extinguishes fire. Plants break apart earth and drains water.
