My idea for a new spell is called the Counter Spell. The name can change because I didn't put too much thought into it. It would cost 30k to prepare and 45 minutes to an hour to train. I'd like it to be available at spell factory level 4 because I think people would use this spell more often than the jump spell.
Basically, upon casting, a 5 tile circle will drop down. While inside of the circle, any damage the caster's troops take will be 'stored' for 7 seconds. At the end of the 7 seconds, all defenses and buildings inside the circle will take damage equal to 60%-80% of the damage that was stored.
I just thought of this and wanted to get it down while its fresh in my head. Feel free to change the name or numbers that you think would be better
This is really OP. The damage would be enough to one hit any building. Put it in the right place, have a golem soak up the damage, and goodbye everything.
