Spell Cannon (Defense)

I know that the idea of defensive spells has already been circulating through the forums but this is a new spin on it!


Description: "Fire spells to support your defenses or do damage to enemy troops!"
Range Radius: 5


Name: Spell Cannon
Town Hall Unlocked: 9
Cost: 2,000,000 Elixer


Spell CannonLvl1 Stats:
Spell Capacity: 3
Firing Speed: 1 every 7s
Hitpoints: 1600


Spell Cannon Lvl2 Stats:
Spell Capacity: 4
Firing Speed: 1 every 7s
Hitpoints: 2000
Cost to upgrade: 2,500,000 Elixer


Spell Cannon Lvl3 Stats:

Firing Speed: 1 every 7s
Hitpoints: 2500
Cost to upgrade: 3,000,000 elixer


How each spells react:
Lightning Spell: Straight Forward except does a bit less damage to make it less OP (say 10-25% less)
Healing Spell: Heals your injured buildings
Rage Spell: Gives your defenses a stat boost of the rage spell
Jump Spell: Can't be loaded
Freeze Spell: Freezes Enemy troops

Appearance: Lvl1: It would look like a spell factory and cannon mix. With the spells swirling in the back and the slot for shooting on the front. Colors are yellow with white stripes
Lvl2: Colors change to gray with white stripes
Lvl3: Colors change to black with yellow stripes


Notes:
- Spells must be manually loaded like x-bows
- Spells can't be reused after being used in a defense but those that aren't
- Traps (other than spring traps) ARE affected by the spell cannon (only really matters with rage though)



Constructive Criticism is appreciated :)
