It is crucial to take mid-control on Ascent as this provides a lot of information to either team.
This off angle is for the defending side, giving them a chance to catch an attacker taking a dry peek down mid.
Jett is a suitable agent to get into the desired position due to her updraft ability which allows her to access this spot.
Use updraft to climb the wall right in front of the spawn which faces mid.
Once on top of the wall, stand on top of the spikes and run straight ahead, followed by a normal jump to reach the corner.
Do not try to shift walk as this will cause the player to automatically fall of the wall.
From this position, an attacker peeking mid can easily be fragged as this is a very unique off angle that is very unlikely to be targetted.
