So, Here's how it went:
I made a friend with a newbie. He was a Burn Kaiser and I was a Burn Thunder Breaker. I was already doing the Ellina Academy theme dungeon, when I heard he wanted to defeat the mole king. I told him I already defeated him, so I helped him out throughout the dungeon. Then, when he fought the mole king, he was disappointed, regardless that I told him it was easy. Suddenly, he wanted to fight Pianus (Yes the fish in Aquarium), and to be honest, he was nagging at me that he wanted to fight Pianus.
Finally, I turned around and asked him, "Why do you all of a sudden want to fight Pianus?" His response, " I WANT A CHALLENGE." And, I was hesitant to take him. I knew where the fish was, but he was so determined and nothing was going to convince him otherwise. So, I said, "I'll lead you to him, but I won't help you fight with him." His response, "(I don't think it was exact but) Whaaa... Why not?" My response, "Because, I know I'll die." Not wavering on his choice to fight Pianus. I finally gave in. "Alright! I'll take you to him, but I will do it on my warrior. Head to Aquarius and I'll meet you there." So, I got on my warrior, but I noticed there was a time he was struggling fighting the seals.He was complaining that he could only kill 10 during the time I was preparing. This would of been the perfect time to back out, but I guess I did say, "Well, we already got this far into the game, no point turning back now." he nodded. I protected him to the cave to Pianus, and what I feared would happen.... happen... He died. I tried to revive him, but I noticed we were not at a party together for some odd reason (He was in a party with my pirate no knight). So, he wanted to go again. So, I did it. He died again, but this time I revived. Right about the time when I tried to warn him to be careful not to die again due to my revival limit. He died again. I asked, "Hey dude are you okay? Do you want me to handle him for you?" I was starting to feel concerned. He told me he wanted me to get rid of it and I did so. After that, it felt like he went very quiet like speaking to a different person.
He also talked to me less. I don't know what I did wrong or did I do anything wrong?
