Make a bridge of ice across a body of water and have your enemies chase you across it. To do this easier, cast Ice magic on water or a river. When you have finished crossing the body of water and while your enemies are still on it, cast Fire magic where they are standing to melt the ice. They will not be able to move and will drown in three turns. Note: This will not work on flying enemies. You can also use Leviathan to make bigger patches of ice. This trick will also work by casting Thunder on existing normal bridges on which the enemy is standing. In the case of Thunder magic, you can destroy a bridge over the sky to kill them instantly.
