The season x with the red orb…the one on the right. Says you can raise your season points and you fight with Elektra. What exactly does this do?
Nothing but get you the rewards listed. There aren’t any season points or anything. It’s just a try-out for Elektra so you can see what she’s like in a match.
Once you do that fight, you can accumulate season points for progression rewards by competing in pvp events and the shield simulator.
You don’t need to do the fight to join the season.
