I personally think it’s going to be a slowness effect. After Mud was scrapped, Vetex said there would be a lost magic that fills its role, and Gravity is an obvious candidate for that. I’m kinda not sure what slowing magic there even could be other than Gravity and Mud. Vetex wouldn’t add Slime Magic, would he???
Personally hoping it’s not just heavier knockback. Especially if it pulls enemies toward you since that’s counterproductive to what magic is supposed to be, primarily a zoning class. Maybe if, unlike Wind, the knockback is always in a fixed direction regardless of where the blast was angled, like if it always sent you downward, that would be useful. I think I’d prefer the other two options more though.
Blasts that pull in enemies would be cool. Very annoying to dodge, though, and you might accidentally pull enemies closer to you which, again, violates the zoning purpose of magic.
I think it’d be cool if it had like inverse knockback, as in the explosion sends you flying into the blast’s centre and slingshots you out. Could be useful as a way to force the opponent into weird positioning
I feel like it’ll add a status effect that essentially gives constant knockback in a certain direction or most likely just downwards, you wouldn’t really be slower you’d just be pretty glued to the ground
