An Apex Legends exploit allows players to reload their weapon in the void if you time it well. It's a rather straightforward bug, but it requires the player to be quick and on their feet. You need to be able to activate and cancel an ability while activating another one.
The exploit was highlighted on the Apex Legends subreddit by Rem-ember_to_flame. The process is about timing, and while it may seem like a small advantage, it's massive for resetting and preparing to fire on your enemy.
To do this yourself on the PC, press Z, cancel by clicking either left click or Z again, then hit Q. This should allow you to be able to reload in the void. The key is to be quick. But don't be surprised if the exploit is patched out as a few different Apex Legends devs were active in the post.
This allows Wraith to function outside of her attended use, so Respawn Entertainment will attempt to fix this eventually. It's just based on when they'll get to it.
