EDIT: Here's a little bit of notes I made for the testing of Rage effect on a grounded Air Slash against Mario. I tested using a handicap on Shulk, had Mario be player 2, dealt enough damage to have the damage meter display the number I needed for testing, & watched what platform Mario would land on after being launched from the grounded Air Slash. I used a custom stage with platforms stacking up high 1 grid unit from each other.
- Shulk at 0 - 46% launches Mario 10 platforms high
- Shulk at 47 - 72% launches Mario 11 platforms high
- Shulk at 73 - 97% launches Mario 12 platforms high
- Shulk at 98 - 120% launches Mario 13 platforms high
- Shulk at 121 - 143% launches Mario 14 platforms high
- Shulk at 144 - 300% launches Mario 15 platforms high
Please keep in mind that decimal percentages are a thing in Smash Bros., so even though the damage meter says 46%, it could be 46.95% which is too close to being 47%. I used Mario Jab1 staled to rack up damage which wasn't the best way.
