Hi all, I've discovered in arena that when my partner dies... there's a slight window to use resurrect in combat. Naturally, there's no way to pull this off against a competent team.. Which is why I'm calling this bubble-rez.
The directions are simple - after one of your teammates dies, immediately bubble and cast Redemption.
Here's a video I made featuring the exploit - BUBBLE REZ! Gamebreaking Arena Exploit + More Shenanigans by Fiveshot - YouTube
Enjoy!
