Cleared the 3rd Day Attendance Hidden Quest!

It was easy because I set up auto-farming and focused on the Expedition Event. I neglected the rare Baekgak card I received on the first day, but when I completed its exclusive mission today, it gave me reward items, and it automatically created 4 equipment slots upon 2nd Transcendence. The Raid Expedition gives you one legendary hero for raid use and a mission to raise them each time you clear stage 3 with a designated rare raid card. I don't know if the rare cards were summoned or given, but I had all 3 in my inventory. With these, I got the legendary raid heroes Sein/Espada/Pascal. By adding them and Baekgak, I can clear up to stage 6 of the raid. I also enhanced my weapons while doing so. Since it's difficult to Transcend Taeo, who I got on the first day, through Wish Summon, I chose Runi on the first day with the daily Legendary Hero Selector given for a week. I think it's better to focus all resources on one hero rather than spreading them thin. I already have Rachel, so I opened 4 equipment slots at 2nd Transcendence and equipped the second free 6-star weapon set, but Taeo and this hero can't be awakened yet ㅜ I awakened Rudi, and I want to get Delonse too. Taeo has high attack power, skill reservation 1 2
