NOTE: It's per Shot fired, splash damage buildings only take damage for every shot they fire, inferno towers are unaffecte by this spell

How would leveling work:At level 1, the defense would take 25% of the damage, level 2, 35% and so on

Radius: 3 Tiles (so 6 tiles wide at its widest point)
Time: 10 seconds

Spell Factory Unlocked: 5

On a side note, the numbers don't specifically matter, it's more the concept
