For days I searched for the fastest method to gain XP to no avail, the method every video showed was going to the Invasions mode and entering Fengjian Village, entering an endurance challenge, and getting flawless victory with a brutality finisher. With that method, you would get easy kills and a lot of XP pretty quickly which was perfect to level up the Kameos and characters. The problem is, that that method no longer works because the season is over, and Fengjian no longer is available to pick up. But, after countless tries and seeing little to no progress on a single level, I finally found THE BEST METHOD IN THIS SEASON. 1. Go to the Sung Woo Festival Mesa. 2. Unlock the Windbreaker talisman. 3. Go to Portal Gateway, and once inside go to the seasonal tower. 4. Reach level 56 on the tower. 5. Watch the XP you get after every fight, which is more than a thousand. For a more detailed explanation, watch the video so you too can get a ton of XP in little to no time.
