Honestly kinda difficult to pull off, but you could probably pull it off consistently with practice. Lmk if this is already known. Another thing I found out during this that's probably already known that I just wasn't aware about, is that sometimes this will desync the grab and the throw of one climber will be perfectly timed so that the other climber then grabs them and throws them for an almost 20% true combo.
- You can do it anywhere on the map - Only tested on Ultimatum as of currently - Tested on SG and CE, Im assuming it works for all at least non-short characters
