Not quite a trick!

When playing any map move your shaman towards the enemy and click past the enemy shaman.
Have the enemy shaman in view on your screen.
Have the pointer with the shaman selected ready to run back.
Once the enemy's shaman jumps run back quickly.
If you do it right u should dodge the first light.
This is good for haveing the enemy waste their mana.
If you are lucky u may dodge more than one light.
