You probably already know that Launch is a pretty powerful skill but have you seen its true potential? There is a bunch of different techs you can use to access difficult pickups or simply going faster.
Launch Swap
If you unequip Launch just after using it, your launch will be faster and will go further than usual. You can equip Launch again at any time after releasing your weapon wheel once.
Boosted launch
When you change your direction in the air, Ori plays a little turnaround animation. If you launch during that animation, your launch will keep its initial speed a bit longer, making it go further. In order to perform it: jump in a direction, press the opposite direction, launch in the same direction as your jump and keep holding the direction you pressed before using launch. Which means:
- Boosting to the right: jump right, press left, launch somewhere to the right of Ori, keep holding left
- Boosting to the left: jump left, press right, launch somewhere to the left of Ori, keep holding right
You can glitch out Ori's turnaround animation by either touching a wall just after exiting water with water dash, touching a wall just after exiting sand with burrow's dash or entering sand immediately after exiting it. If it happens, you won't be able to do boosted launch. To fix it, you can either re-enter water or sand or reloading your save file.
Weapon Launch
If you do a Launch upward and an upslash on the same frame, your Launch will go further. You can do it with both Sword and Hammer but Hammer Launch are more powerfull than Sword Launch. Both can be use midair but you will need to use your Sword upslash if you want to do a Sword Launch midair. It's recommended to set up a bind to perform them more easily. You can combine it with a Launch Swap to go even further.

Terrawalk
When you use launch on a slope, you will maintain some of Launch's speed. This is mostly use in order to go faster.

Ceiling Launch
Like Terrawalk, if you use launch on a slope in the ceiling, you will maintain some of Launch’s speed. This is mostly use in order to go faster.
Launch Glide
This trick is exclusive to keyboard and mouse control, but you can bind your second stick as a mouse if you want to use it on a controller. If before using Launch you release your directional input after doing either a backflip, releasing a bash or doing a reverse dash, you will preserve some of your Launc's speed. This is mainly use go to faster and can be combined with a launch swap to go even faster. Launch Glide can be executed with a controller on the Switch version but not possible on the Xbox or PC version.
