A large buzzsaw blade moves across the ground. Each upgrade adds an extra buzzsaw, up to 7 total. Unlike other Splash spells, the first version has full range, and each upgrade adds an extra blade but not extra distance. Each blade can do 4 hits on enemies that aren't knocked over, unlike the typical Splash spell that does 1 hit per upgrade level.
Each buzzsaw spawns at a random size and distance from you, and some may start slightly behind you and not go as far. At max upgrade, this means the spell can protect you from both sides somewhat. The buzzsaws also take a while to finish after the casting animation is complete, so you can move away just after casting it while the buzzsaws continue to deal damage from where you were before.
Buzzsaws completely ignore all terrain including pits, slopes, walls, and the line in the volleyball game. This is another feature unique to them.
This is the most powerful spell for defeating enemies that aren't knocked over, due to the number of hits. This makes characters using this spell able to defeat ground-based bosses in mere seconds. Even taking enemies that are knocked over into consideration, the spell is still overpowered because of the incredible crowd control capabilities.
When at max potential, this attack does approximately 2.9x more damage to any enemy that receives chain damage than the next most powerful splash attack, but at the same time it yields four times as much XP per cast of magic, making it the most effective form of magic for XP farming on bosses Catfish/Painter. Also, at maxed magic, when the splash is spammed, it can eviscerate Catfish before it even spits out a furball, but only on Normal Mode.
The only Splash Attacks that come remotely close in the same fast killing power ranks are Snakey and Brute's Thorny Vines, Ninja's Smokescreen, and, to a lesser extent, Fire Demon's Flaming Pillars.
