My characters were under-leveled in many instances, and I had to restart fights a few times. But I remember one event, Legend of the Vagabond, that shattered my pride in my characters. Here's how it went. I had got Zhongli and crowned his elemental skill and elemental burst. Now the players who have Zhongli know how strong his shield and potency are in the fight. I was ready to initiate a challenge where I had to face three Maguu Kenki where one was a standard variant, one was a cryo, and the last one was anemo. The challenge just started, and all of a sudden, all three of them went into a slash frenzy mode. I had no time to react, and they slashed my Zhongli like a game of fruit ninja. I thought I could take them on a greater difficulty but I couldn't even tank the damage, let alone fight them. I still remember it crystal clear and told my friend to complete the challenges for me. That event scarred me, and since then, I'm paranoid about new events with varying levels of difficulty. I mean, co-op for the win! At least I won't be the only one suffering.
