Question: Anyone know how to aim the decoys that Tricksters make as a special move?
The direction that you were moving in will be the same direction that your decoy will continue to go on, for the same tiles that you were moving for. It has, however, a certain time span (or is it decided by tiles? I don't know) before the activation in which those actions are copied, but those behind it are not.
For example :
Moved 5 tiles, used decoy, decoy moved 5 tiles.
Moved 999999 tiles and took a lap around the beach; the Decoy will not follow all of that, but only a few tiles.
That's purdy much it. To learn how decoy works, I'd suggest using rotation and off - screen, so you can have more tiles for you to use and a longer view to watch your decoy and learn how it works. (You'd also do well in taking the initial prism for teleports and higher tiered prisms for actual decoys.)
