Impact Spell
This spell has effects on the first ground in a target route that is not destroyed. It can instantly destroy non-protected grounds (=without buildings on them.). Unless you really don't have enough power, bomb birds are usually enough to break the grounds and the buildings.

Healing Aura
A very useful spell that heals units.

The area of effect of this spell will slowly move following the target route from the start to the end. Even units sent at the previous routes will be healed. So, you can trace another route just for healing after sending units.
