I want to know how i can make one certain title variable "Dalaran Grass Trim" turn into "Icecrown Ice" Does anyone know how to perform this trigger?

The action is:


Code:

Environment - Change terrain type at (Point) to Icecrown Glacier - Ice using variation -1 in an area of size (size) and shape (shape)

There is no way to convert them - what you have to do is check points on the map in a grid (based on the size of the tile) to first find out which terrain type is there - like so:


Code:

If:
(Terrain type at (Point)) Equal to Dalaran Ruins - Trim Grass
Then:
Environment - Change terrain type at (Point) to Icecrown Glacier - Ice using variation -1 in an area of size (size) and shape (shape)
