"Shocking... Positively Shocking"
Using Rachel, shocked your opponent more than 15 times during a single combo
This one may sound like it's a bit of a pain in the rear however it's actually quite simple. First, you must build your heat meter to 50. Do this by attacking of instant blocking attacks from a friend or second controller. Then, do a quarter circle forward (236) + A (Square on default controls). Do this three times and make sure the stems are all close to each other. Once this is done, move the second player to the stems.
You'll want to do a quarter circle back (214) + A next. This will send out a toad who will approach the enemy and shock them. As soon as the shocking begins, you'll want to quickly perform a Half circle back, forward (632146) + C (Circle). The toad will electrocute the enemy for a few hits and the distortion will activate the stems adding up to a grand total of 20 shocking hits. You have to be fairly quick or else the toad will end before the distortion works causing the combo to go blue.
It's highly recommended you do this against a second controller or a friend who is playing against Tager.
