Easily killing himself in the process when you utilize the mediumweight juggle. The Evil Wizard in his final phase deals 150 damage to himself every time he hits himself with his own fire meteors. Though in order to use the Snow World method effectively, you must have minimal to no strength, and an extra controller along with a character who already has Snow World unlocked in Insane Mode so you can bring the character you wish to level up to Snow World early. The most efficient XP grinding spot is repeating the first wave of Snow World, and juggling all of the enemies at once against the ice tower on the right, generating a surplus amount of extra, low-damage hits.

For most players, this is the preferred XP grinding spot with all characters.

By farming the Troll Mother on Insane Mode, you can get to level 99 in less than two hours you just have to never upgrade Strength. By never adding to Strength, you can level between 5~6 times faster than a player with more Strength, and a great place to grind XP is the Troll Mother, which is reached very early in the campaign. While the "x10 Rule" seems like a huge obstacle to success, with ten times more health per enemy, you also get ten times more XP per enemy because you have to hit them ten times more to kill them.

Some examples are: Painter having 5x health and his paintings having 3x health and doing 5x damage, Corn Boss having 5x health, certain enemies doing half damage (Ex: All enemies in the Necromancer Fight), etc. There are multiple exceptions to this rule however.

On top of that, most enemies' damage is multiplied by ten (enemies that deal 4 damage normally will deal 40, enemies that deal 35 normally will deal 350, etc.). Most enemies' health on Insane Mode is multiplied by ten enemies with 50 health normally will have 500, enemies with 350 will have 3500, etc.
