Player can use six different "Effect Spells". These spells do nothing other than cause a small animation to appear briefly. These effects neither harm nor benefit players, they are simply decorative, and just for fun.
These spells are located by first clicking the toolbox button on the player's toolbar, then the bottle-rocket button. Simply click the button to select the spell you wish to use, then click the game board where you want the effect to be centered. The spell will play for a few seconds, then disappear.
