Spell Factory Option to Use One Spell on Defense
What do you think about this? In the spell factory you can mark one of the spells you made to be used on defense. The spell factory would have a defensive radius similar a rage spell so it can only defend the buildings next to it. The defensive spell would trigger like a trap does. The spell factory would then be a very strategic defensive building.
For example:
Rage Spell: The defensive buildings around the factory gain extra DPS
Heal Spell: Heals nearby buildings
Lighting Spell: Damages attacking units
Jump Spell: Prevents units from jumping over walls under the spell area
Freeze Spell: When spell factory is destroyed, all units around it are frozen temporarily
