Idea: gravity spell

The idea is: enemy are affected by higher gravity, air troops and heros are stunned and grounded(so they could be hit by things that usually can't target air) for the duration and ground troops lose the ability to hop over walls.

Against defending cc troops they'd get trapped by walls if they're ground troops or just outright stunned if air so it could combo well with poison

I also thought it could be a cool hidden effect if you hit an area with air traps they wouldn't activate while the effect lingers and another idea that units affected take increased damage from earthquake spells

This came from thinking about spell tower upgrades so obviously that could work too

Lemme know if it's a cool idea or not
