Spell Affects Your Own Units
So kind of like Boom Beach, The spells that you lay down would affect your own troops. There would be only 3 spells that would change. The Lightning Spell, Rage Spell And Freeze Spell would all all do something to you troops/enemy troops.
Lightning Spell
The Lightning spell would damage you troops with as much damage of how it will normally cast.
Rage Spell
The rage spell would only change by enraging enemy's clan castle reinforcements/Heroes.
Freeze Spell
Freezes your own troops/Heroes
