spell factory providing defensive spells
the spell factory has an area it can shoot spells, (most likely the same radius as healing spells circles) and depending on the level of spell factory you are able to buy (like you buy offensive spells) a defensive spell that might hurt troops, slow them down, weaken them, or completely freeze them. every time you get attacked and the defensive spell is used up you must go in and re-buy the spell (exactly like you would re-arm traps). you will also be able to research them in the laboratory to make them last longer and/or be more powerful
the spells might go like this...
-level 1 factory has slow down spell which takes off 5 speed (researched it will half the speed of the troop)
-level 2 factory also now has weaken troops which takes off 5 damage (researched it will half damage)
-level 3 factory also now has hurt troops which has 30 damage per second (researched it will have 40 damage per second)
-level 4 factory also now has freeze troops which will completely freeze troops movement and attacking ability for 5 seconds (researching will add a half speed slowness effect after for the rest of there lives)
if spell factory is set off maybe archers deployed can destroy the spell factory and release the trapped troops from all ailment immediately (even researched freeze troops)
cost will be decided by Supercell
